R Question

What does "Error in tools:::httpdPort <= 0L : ...." in Rstudio means?

I have upgraded R to version 3.2.2.
When I restart Rstudio, before ">" is shown, there is an error message:

Error in tools:::httpdPort <= 0L :
comparison (4) is possible only for atomic and list types

What does this mean? What should I do to remove this message?

Upgrade your RStudio version to the latest one, should work in any OS.

For Linux/Ubuntu 14.04 terminal users, simply do:

sudo apt-get remove rstudio

wget https://download1.rstudio.org/rstudio-0.99.489-amd64.deb

sudo dpkg -i rstudio-0.99.489-amd64.deb

Now, run RStudio. The error message should disappear.
