System details

RStudio Edition : Desktop
RStudio Version : 2023.06.0 Build 418
OS Version      : Windows 11
R Version       : 4.3.0

Steps to reproduce the problem

I'm not sure I can reproduce this on demand, it seems to come up randomly.

Describe the problem in detail

At the end of seemingly any block of code, there is a chance of throwing these two errors:

Error in exists(cacheKey, where = .rs.WorkingDataEnv, inherits = FALSE) : 
  invalid first argument
Error in assign(cacheKey, frame, .rs.CachedDataEnv) : 
  attempt to use zero-length variable name

I'm sorry I can't be of more help; I haven't divined any pattern to this error. But since the environment it's happening in is named ".rs.", I figured it might be caused by the daily build of RStudio I'm using. I'm using this version because the public build keeps crashing because of the dataframe autocompletion preview when I'm working with large data.

Describe the behavior you expected

• I have read the guide for submitting good bug reports.
• I have installed the latest version of RStudio, and confirmed that the issue still persists.
• If I am reporting an RStudio crash, I have included a diagnostics report.
• I have done my best to include a minimal, self-contained set of instructions for consistently reproducing the issue.

I was able to reproduce this with 2023.06.0+421 on Mac 13.1

1. Trigger error from data.frame preview with multiple AsIs fails #13215
   1. Run df <- data.frame(X = I(matrix(c(1,0,0,1),2)), W = I(matrix(c(1,-1,-1,1),2))) in console
   2. Type df in console, then hit tab key to trigger autocomplete
   3. Get error

      Error in .subset2(x, i, exact = exact) : subscript out of bounds
      Error in if (maxRows != -1 && nrow(data) > maxRows) data <- head(data,  : 
        missing value where TRUE/FALSE needed
      

2. Run rm(list = ls()) in console
   • Get error

     Error in exists(cacheKey, where = .rs.WorkingDataEnv, inherits = FALSE) : 
       invalid first argument
     

@jonvanausdeln was able to reproduce using these steps on Windows as well

Thanks @sharon-wang!

As a workaround, I think you can add the following to your ~/.Rprofile:

options(rstudio.help.showDataPreview = FALSE)

and then restart the RStudio session and confirm that getOption("rstudio.help.showDataPreview") reports FALSE.

@jwe4ec , thank you for the report and repro steps. I've opened a new issue (#13291) to track this problem.

[kevinushey]

What functionality is lost (if any) if we turn off showDataPreview as suggest by @kevinushey above?

The only thing that's lost is the inline data preview that displays in the completion help popup, when a data.frame is selected in the completion list.

@LewisT1987 did you read the instructions posted in the OP of this issue thread?

@kevinushey I tried your workaround because I'm working on a server instance where I don't have the ability to update RStudio without going through a system administrator. Adding what you suggested to the .Rprofile worked!

[kevinushey]

@kaijagahm Phew, I'm glad to hear that was able to help!
