Hi,
I have a couple of quick questions regarding R.
1) I have a ".First" function that automatically loads the quadprog package into the
workspace. The .First function resides in R and is only saved if I save the workspace.
The exact function is as follows:
.First<-function()
{
library(quadprog)
}
Is there any way that this function can be saved outside of R? That is, is there any
procedure that will run specified R commands whenever R is invoked?
2) Is there anyway to specify additional paths for R to search. For example, I have
some R script named, myProg.r that is saved in a directory C:\Programs\RLanguage\Rob\.
I run the script in the following way:
source("C:/Programs/RLanguage/Rob/myProg.r")
This works fine, but I was wondering if there is any command that could be entered
into the .First function described above that adds the directory
C:\Programs\RLanguage\Rob\ to the R path. This way, C:\Programs\RLanguage\Rob\ will
always be checked for the code and I could simply run myProg.r as follows:
source("myProg.r")
3) Is there anyway that I could save functions that I have written outside of R. That
is, could I write functions and have them saved in some directory, such as,
C:\Programs\RLanguage\RobFunctions\? This way I would be able to copy the functions to
other pcs. This is very simple in MatLab. Please let me know.
Thanks for the help.
Rob
