[R] how to get a value from a list (using paste function)?

[Soyeon Kim]

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!
