Rstudio在编辑脚本时将错误输出到控制台

Question

I am working on a project on Rstudio and something wired has become to happen: each time I write something into a script Rstudio automatically writes the following error into the console:

Error in rep.int(vectorNames[i], length(vector[[i]])) : 
  unimplemented type 'NULL' in 'rep3'

and a label appears under the cursor: "R code execution error". Appart form this visual bug, everything is working properly. Does anyone have the same issue ?

Answer 1

I've just experienced this issue. In my case, I guess it must be related to the NAMESPACE file from the package.

I can see a discussion about this subject here on R Studio support site .

Citation from the source mentioned above:

There are two times when we run the code that could be emitting this error:

• When attempting to retrieve completions from the package's NAMESPACE file,
• When attempting to retrieve completions for native routines (eg for within a '.Call()' call).

Can you recall if you had been editing the package's NAMESPACE file before seeing this error? Alternatively, have you been using 'devtools::load_all()' or other similar machinery?

And to clearly answer your question: Yes! I am having the same issue! (Damn it! :) )

LATER EDIT:

I've got rid of the problem by closing the project and reopening it again.
