When opening file, console shows pink background with red dots

[shillate]

When I attempt to open a file, all I get is a pink background with red dots

Any idea what may be causing this?

Hi @shillate! Welcome!

Three things that might be helpful here:

1. A screenshot
2. Steps to reproduce the problem. This might look like:
   • Share a file where this happens (post on Google Drive, Dropbox, Github, etc)
   • Describe exactly what you do when opening the file
3. Run an RStudio diagnostics report: rstd.io/support-diagnostics-report
   If the output isn't too long, you can paste the result in here. Please use the little </> button at the top of the posting box to format what you paste (keeps the forum software from garbling it!). If the output is too long to paste in here, please share it online somewhere else and post a link.

Also, is this sort of like what you're seeing? (Click the down arrow to expand the preview so you can see the screenshot)

Pink dots appear in files and unable to save files intermittently MacOS High Sierra

I don't have all the info you requested, but here is a screenshot from this morning. [Snip20180525_1] The x error from RStudio is: unexpected token '' This is a file that was on my Desktop, so no network drives were involved. When I view the characters in terminal using a more command, here is how they appear: ^@^@^@^@^@^@^@^@ Running the code works with no errors caused by the pink dots. So, the problem is one of annoyance and confusion about the code having errors.

(Unfortunately, I don't think there was ever a resolution to the problem described in that topic)

Thanks! How odd.

Does this happen with all types of files (.R, .Rmd, .txt), or only certain types of files — or only certain individual files? Can you post a file that displays this behavior somewhere (e.g. Google Drive, Pastebin, etc) and link to it?

[shillate]

This happens only with this one .Rmd file, but the other files can be painfully slow. I did a Microsoft memory scan/optimization and this seemed to do nothing. This all seemed to begin when I upgraded to the newest Rstudio version.

When I run the GPU diagnostics, it says the following:

Those pink dots are used as replacement characters for data in the document that couldn't be decoded -- in other words, it's typically a sign that the document has become corrupted and replaced with garbage data.

If it only occurs for one file, then it would seem that one file somehow became corrupted -- your best bet would be to restore from backup.

So had to stop a random forest model (ranger using caret) that had been running for 17 hours on parallel (expected time duration was 2-3 hours based on similar models) and when the CPU usage didn't go down after having stopped the process, I decided to close RStudio and shut down my computer. Now when I open the R project in question, every rmarkdown file within the project opens up looking like this. All the R scripts seem ok.

Am I to understand that each and every .Rmd file within the project is corrupt and beyond salvage? [sobs uncontrollably on the inside]

Any and all help appreciated.
