RStudio opens documentation in web browser

Question

When I type in the name of the function the help box in RStudio I get the answer opened in the web browser instead of RStudio-help window. The same happens when typing in ?function for example ?which . While doing so I also get the following error in the console:

> ?which
Error in (function ()  : attempt to apply non-function
Error in (function ()  : attempt to apply non-function
Error in (function ()  : attempt to apply non-function

This happened after upgrading R to version 3.1.3 and I'm on Ubuntu 14.04.

Does anyone know how to fix this - how to make RStudio open the documentation in RStudio window, not in the web browser?

Answer 1

RStudio needs to be upgraded to 0.98.1103 or newer version. The answer was taken from here

Answer 2

in R, this works

options(help_type = "text")

in R Studio, you can open the file RStudio\\R\\Options.R and comment out this part (in my current version line 16-20):

# custom browseURL implementation
options(browser = function(url)
{
    .Call("rs_browseURL", url) ;
})
