Whenever I run plot(...), R responds as:
Error in gzfile(file, "wb") : cannot open the connection
In addition: Warning message:
In gzfile(file, "wb") :

Graphics error: Plot rendering error
looked into the directory, and there were no files existing. How can I fix this problem??
Does this work for you in R, but not in RStudio? (see FAQ below for disambiguation)
works fine in R, I only encounter problems when using rstudio
Some of the suggestions in this thread might be helpful (e.g. checking permissions, anti-virus software, etc):
Thanks for the bug report -- indeed, RStudio has trouble with its graphics device for Windows users who have non-ASCII characters in their username. This occurs because the temporary directory (where RStudio attempts to write its plots) typically resides as a subdirectory of the user's home folder, and because that full path contains non-ASCII characters, we run into this issue.
AFAIK the best workaround is to modify the temporary directory to point to a directory outside your home directory, e.g. you could set an environment variable:
TMPDIR = C:/tmp
