If you are experiencing an issue with a CRAN package on Debian where you can view a photo in Windows but not in Debian, the problem could be related to the image library used by the package or differences in the operating systems' configurations.

Here are some potential steps to troubleshoot and resolve the issue:

  1. Check Package Dependencies:
    Verify that the package you are using has all its required dependencies properly installed on Debian. Some CRAN packages may rely on external image libraries, and missing dependencies could lead to issues with image handling. Install any missing dependencies using the package manager (apt).

  2. Image Format Compatibility:
    Ensure that the image format used in the package is compatible with both Windows and Debian. Common image formats like JPEG, PNG, and GIF are widely supported, but some less common formats might not be compatible with all systems.

  3. Update CRAN Package:
    Check if there are any updates available for the CRAN package that might address the image display issue. You can update the package using the install.packages() function in R.

  4. Check Image Paths:
    Verify that the image file paths used in the CRAN package are correct and accessible on Debian. Differences in file paths or case sensitivity between Windows and Debian could cause issues.

  5. Image File Permissions:
    Ensure that the image files are accessible and have the appropriate read permissions on Debian. Use the chmod command to modify file permissions if needed.

  6. Check Image Libraries:
    Confirm that the image libraries (e.g., libjpeg, libpng) used by the CRAN package are installed and functional on Debian. You can use the package manager (apt) to install any missing image libraries.

  7. Check Locale Settings:
    Differences in locale settings between Windows and Debian could affect image display. Ensure that your Debian environment has appropriate locale settings.

  8. Test Other Images:
    Test the CRAN package with different images on Debian to see if the issue is specific to a particular image or a general problem with image handling.

  9. Consult Package Documentation:
    Refer to the package documentation and user forums to see if others have encountered similar issues and how they resolved them.

If the issue persists after trying the above steps, you may want to seek help from the CRAN package's maintainers or the R community to get further assistance and guidance in troubleshooting the specific issue.
