[R] Not able to save .Rhistory

[Laurie Sindlinger]

Hello all,

    I am an R beginner, and I have not been able to save my history when 
using R. When I try to use the command that is shown in the help pages:

savehistory(file = ".Rhistory")

I receive an error message:

Error in savehistory(file) : no history available to save

Do any of you have suggestions on what the problem may be? Are there a 
minimum number of lines that can be saved? A file called .Rhistory is 
created in my working directory, but there is nothing inside of this 
file. This is the set-up that I am using:

platform   sparc-sun-solaris2.9
arch         sparc
os            solaris2.9
system     sparc,solaris2.9
status
major       1
minor       7.0
year         2003
month       04
day           16
language    R

Thanks so much for your time!
