1. I have a R program in a file say "functions.R".
I load the "functions.R" file the R using source("function.R") and then call
functionsf1(), f2() etc. which are declared and defined within "function.R"
file.
I also need to load a couple of R libraries using library() before I can
use f1(), f2() etc.
My question is can I acheive all this (i.e. calling function f1() and f2())
from the windows prompt without opening the R environment ? If yes then how?
Put all the code into a file, e.g. "foo.R", and run
R CMD BATCH foo.R from the windows command shell.
2. Also, Is there any way to scan strings directly. Like scan() function
only scans numerical values. Is there any way to scan strings?
Yes, it is called scan() which is for arbitrary data, including
character(). See ?scan. Otherwise, you may want to look into ?readLines
