Error when trying to convert data frame into a csv file in R

Question

I'm trying to convert a data-frame to csv file and while I do that I get the following error, why is that so?

write.csv(packages, file = "packages.csv", row.names = FALSE)
Error in file(file, ifelse(append, "a", "w")) :
  cannot open the connection
In addition: Warning message:
In file(file, ifelse(append, "a", "w")) :
  cannot open file 'packages.csv': Permission denied

Answer 1

If packages.csv file is open on your system, close it and execute this command again. This should work.
