No, never ever!
There is an R idiom made for it:
cvtest[[lambda.rule]]

I hope this works.

A possible solution:
get(lambda.rule,envir=list2env(cvtest))

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
