I have been experiencing the same problem, and have found that it is caused by a bug in RStudio (the code runs fine in R and R-gui, but fails in RStudio.) It is hard to reproduce until something gets corrupted in RStudio's saved state, after which the behaviour is pretty consistent.

Removing ~/.rstudio-desktop fixed the issue for me.

mv ~/.rstudio-desktop ~/rstudio-desktop.old

Answer 3

I am also using Rstudio and get the same error message when running for loops.

Error: unexpected '}' in "}"

If I source the file, like this...

source('~/.active-rstudio-document')

or if I simply click the "source" button in the GUI, I don't get the same error message.

If sourcing the whole R script is not an option, consider copying the for loop to another file and sourcing that.
