Troubleshooting survplot Issues After R and ggplot2 Updates

Have you encountered issues with survplot after updating R and ggplot2? You're not alone! Many users have reported similar problems, and this article aims to provide a comprehensive guide to troubleshoot and resolve these issues. We'll explore common causes, potential solutions, and best practices to ensure your survival plots are back on track.

Understanding the Problem

The survplot function, often used within the survminer package, is a powerful tool for visualizing survival analysis results. However, updates to core R packages like ggplot2 can sometimes introduce compatibility issues. When survplot malfunctions, you might encounter errors, distorted plots, or simply a failure to generate the expected output. It's crucial to first understand the root cause to apply the correct fix. Let's dive deep into the common scenarios and their solutions.

Identifying the Error Messages

One of the first steps in troubleshooting is carefully examining the error messages. These messages often provide clues about the nature of the problem. For instance, an error message like "! Problem while converting geom to grob" suggests an issue with the graphical rendering process. Error messages may seem cryptic, but they pinpoint where the problem occurred.

In the reported case, the error message:

Error:
! Problem while converting geom to grob.
ℹ Error occurred in the 3rd layer.
Caused by error in `draw_group()`:
! Unable to check the capabilities of the windows device.

This indicates a problem with the graphical device, specifically within the windows device on a Windows operating system. This can sometimes occur due to permissions or conflicts with other graphics libraries.

Checking Your R Version and Package Versions

Before diving into complex solutions, ensure your R version and package versions are compatible. Outdated packages or an R version that doesn't align with the package requirements can often cause issues. Check your installed packages and update them if necessary.

Using sessionInfo() in R is a great starting point. It provides a detailed overview of your R environment, including the versions of installed packages. This information is invaluable when seeking help from the community or consulting package documentation. The sessionInfo() output shared by the user shows a transition from R version 4.0.1 to 4.4.0, and a corresponding update in survminer from 0.4.9 to 0.5.1, along with numerous other package updates. This information helps narrow down potential issues related to specific package versions.

sessionInfo()

This command will output a list of your R version, operating system, and attached packages with their versions. Compare this information with the package requirements listed in the documentation or online forums.

Common Causes and Solutions

Now that we've established the basics, let's explore some common causes behind survplot issues after updates and their respective solutions.

1. Graphics Device Issues

As the error message suggests, problems with the graphics device can prevent survplot from rendering correctly. This is particularly common on Windows systems.

Solution:

Restart R Session: A simple restart can sometimes clear temporary glitches with the graphics device.

Use a Different Graphics Device: Try using a different device like x11() (if on a Unix-like system) or explicitly specifying a device like png() or pdf() to save the plot to a file. This helps isolate whether the issue is specific to the windows() device.

# Try saving the plot to a file
png("survplot.png", width = 800, height = 800)
ggsurvplot(f3, cumevents = TRUE, cumevents.col = "strata", fun = "event", title="Healing times comparison by treatment", xlab = "Fortnight", ylab = "Healed patients' percentage", surv.scale="percent", conf.int=TRUE, cumevents.title="Healed patients", legend.title="", surv.median.line = "hv", legend.labs=c("Control","Ozoile"), pval=TRUE, pval.method=TRUE)
dev.off()

Update Graphics Drivers: Outdated graphics drivers can cause conflicts. Ensure your drivers are up to date, especially if you've recently updated your operating system or R.

2. Package Incompatibilities

Updates to ggplot2 can sometimes introduce changes that affect how other packages, including survminer, interact with it. This is a frequent cause of post-update issues.

Solution:

Update All Packages: Use the update.packages() function in R to update all installed packages. This ensures you have the latest versions, which may include compatibility fixes.
```
update.packages(ask = FALSE, checkBuilt = TRUE)
```
Reinstall survminer and Dependencies: Sometimes, a clean reinstall of survminer and its dependencies can resolve conflicts. This ensures all components are correctly installed and linked.
```
remove.packages("survminer")
install.packages("survminer", dependencies = TRUE)
```
Check for Specific Compatibility Issues: Consult the survminer documentation and online forums for known issues with specific ggplot2 versions. There might be patches or workarounds available.

3. Changes in Function Arguments or Syntax

Package updates can sometimes introduce changes in function arguments or syntax. This can lead to errors if your code relies on outdated usage.

Solution:

Review Function Documentation: Carefully review the documentation for ggsurvplot and other related functions. Pay attention to any changes in argument names, default values, or syntax.
```
?ggsurvplot # Access the help documentation for ggsurvplot
```
Adapt Code to New Syntax: Adjust your code to match the updated syntax and argument structure. For instance, the warning message about size being deprecated in ggplot2 suggests replacing it with linewidth.
```
# Example: Replacing size with linewidth
# Old code:
# geom_line(size = 1)

# New code:
# geom_line(linewidth = 1)
```

4. Data Structure Issues

Sometimes, the issue might stem from the structure of your data. If the data frame used in survfit or ggsurvplot has changed, it can lead to errors.

Solution:

Verify Data Structure: Ensure the data frame passed to survfit and ggsurvplot has the expected columns and data types. Use functions like str() and head() to inspect your data.
```
str(rigenoma) # Check the structure of your data frame
head(rigenoma) # View the first few rows of your data frame
```
Address Missing Values: Missing values (NA) can sometimes cause issues. Ensure missing values are handled appropriately, either by imputation or exclusion from the analysis.

5. Namespace Conflicts

In complex R environments, functions from different packages can sometimes have the same name, leading to namespace conflicts. This can cause unexpected behavior.

Solution:

Use Explicit Namespace Referencing: Use the :: operator to explicitly specify the package a function belongs to. For example, instead of ggsurvplot(), use survminer::ggsurvplot().
```
# Example of explicit namespace referencing
survminer::ggsurvplot(f3, ...)
```
Check for Conflicting Packages: Be mindful of the order in which you load packages. Loading a package later can sometimes overwrite functions from previously loaded packages.

Applying Solutions to the Example Case

In the provided example, the error message points to a problem with the Windows graphics device. Based on the common solutions discussed, here’s a step-by-step approach to address this specific issue:

Restart R Session: This is the simplest first step and often resolves temporary glitches.

Try a Different Graphics Device: Save the plot to a file using png() to see if the issue is specific to the windows() device.

png("survplot.png", width = 800, height = 800)
ggsurvplot(f3, cumevents = TRUE, cumevents.col = "strata", fun = "event", title="Healing times comparison by treatment", xlab = "Fortnight", ylab = "Healed patients' percentage", surv.scale="percent", conf.int=TRUE, cumevents.title="Healed patients", legend.title="", surv.median.line = "hv", legend.labs=c("Control","Ozoile"), pval=TRUE, pval.method=TRUE)
dev.off()

Update Graphics Drivers: Ensure your graphics drivers are up to date.
Update Packages: Use update.packages(ask = FALSE, checkBuilt = TRUE) to update all installed packages.

Reinstall survminer: Remove and reinstall survminer along with its dependencies.

remove.packages("survminer")
install.packages("survminer", dependencies = TRUE)

Address the Deprecation Warning: Replace size with linewidth in any relevant geom_line() calls within ggsurvplot customization, though this is just a warning and not the primary cause of the error.

Best Practices for Preventing Future Issues

Prevention is always better than cure. Here are some best practices to minimize the chances of encountering survplot issues after updates:

Regularly Update Packages: Keep your packages updated to benefit from bug fixes and compatibility improvements.
Test Updates in a Controlled Environment: Before updating packages in your primary analysis environment, consider testing them in a separate environment or on a development machine.
Read Release Notes: When updating major packages like ggplot2 or survminer, review the release notes for any breaking changes or known issues.
Use Version Control: Tools like Git can help you track changes in your code and environment, making it easier to revert to a working state if an update introduces problems.
Document Your Environment: Keep a record of your R version and package versions. This information is crucial for reproducibility and troubleshooting.
