Re: [R] .Rprofile vs. First (more of an opinion question)
Hi Erin, If you want to use .First, just put it in the directory where you start up your R session, use it to change all the options that you want for all projects, then source a file to switch to the directory that you want. I call mine SelectAnalysis.R and it just displays a list of current projects from which I select one with a letter key.

How do you create your .First() function and get it into your workspace? I may be confused here, but I think that you would need to make sure that this is done in each workspace (in each working directory) that you use. It may be the case that you use only a single working directory, but it is generally good practice to use a different working directory for each separate project that you engage in. In contrast, putting your settings in .Rprofile causes them to be applied in any working directory in which you start R. I also think that there's more danger of .RData getting lost or over-written --- it is getting used all the time, whereas .Rprofile just sits there and does its thing once it's been created --- than there is of .Rprofile getting lost or over-written. Consequently my 2 bob's worth is: Use .Rprofile. Of course, this is a case of the blind leading the blind.

[R] .Rprofile vs. First (more of an opinion question)
Hello again I am using R-3.1.2 on Windows 7. I am the only one using this particular computer. My question is probably more of an opinion question. I want to set a repos with the options.
