[R] Setting .Rprofile for RStudio on a Windows 7 x64bit

Mon Apr 17 16:30:57 CEST 2017

I cannot add to the instructions that you have already been given
regarding .Rprofile.

But what code did you use in your .Rprofile to set the prompt? The
posting guide explicitly requests that you provide your code, although
maybe you already did earlier in this extensive thread.

?options

is how it can be set. Did you do this?

So is it possible that RStudio is looking at a different version of R than you believe it should be, perhaps at the 32 bit R versus the 64 bit one? The result at the beginning of this thread makes me think you got the 32-bit one connected to RStudio.

Looking at the responses to the queries above and the ones found below, it appears to me that there are RStudio-specific issues that go beyond what is in the `help(Startup)` or equivalent `help(.Rprofile)` page.  I gave an instance of an SO search upthread and I offer another SO search:

At any rate it would have been more appropriate to respond to the SO answers that were ineffective or to post a question there with full description of your efforts and content of your .Rprofile file and your current environment variable settings.)

Unless they were explicitly told about it, in the manner which you just demonstrated.  The usage gets a mention in "An Introduction to R" --- but I had to search for it.

A search of "An Introduction to R" for "starting" gets seven or eight hits, one of which is relevant.  So it all takes patience and persistence.
