[R] searching for special variables

[Dimitris Rizopoulos]

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
