Dear R-Experts, in my program I have a big workspace. Now I want to look for all variables which have the letters "777" in their name (e.g. ask777first) and afterwards I need to delete those variables. How can I reach this aim? Any ideas, Corinna
one option is use something like the following:
a <- 1:10
b777 <- rnorm(10)
c777 <- letters[1:6]
fit <- lm(b777 ~ a)
a777d777 <- 5
##############
lis <- ls()
rm(list = c(lis[grep("777", lis)], "lis"))
ls()
I hope it helps.
Best,
Dimitris

Try: rm(list = ls(patt = 777)) On 5/3/07, Schmitt, Corinna <Corinna.Schmitt at igb.fraunhofer.de> wrote:> Dear R-Experts, > > in my program I have a big workspace.
