eval(parse(text=paste0("cvtest$",lambda.rule)))
No, never ever! There is an R idiom made for it: cvtest[[lambda.rule]] Uwe Ligges
I hope this works. On Wed, Dec 19, 2012 at 12:57 AM, Thomas Stewart <tgs.public.mail at gmail.com>wrote:

Dear my R friends,
I want to get a number from a list using paste function.
In my example,
lambda.rule <- "lambda.1se"
cvtest is a list (result from cv.glmnet)
and
cvtest$lambda.1se
[1] 1.308973
I want to call the value using paste function.
I used get function but there was an error.
test <- get(paste("cvtest$",lambda.rule, sep=""))
Error in get(paste("cvtest$", lambda.rule, sep = "")) :
object 'cvtest$lambda.1se' not found
Do you guys know how to solve this issue?
Thank you so much in advance and merry Christmas!
Soyeon
