Hi everyone,
I looked around the list for a while but couldn't find a solution to my
problem. I am storing some results to a simulation in a list and for each
element i have two separate vectors(is that what they are called, correct my
vocab if necessary). See below
Version1_<-list()
for(i in 1:5){
Version1_[[i]]<-list(First=rnorm(1),Second=rnorm(1))
}
What I want is to put all of the elements' 'First' vectors into a
single
list to box plot. But whats a more elegant solution to the below?
c(Version1_[[1]]$First,Version1_[[2]]$First,Version1_[[3]]$First,Version1_[[4]]$First,Version1_[[5]]$First)
since i have 50 or more simulations this is impractical and sloppy. Do I
need to store my data differently or is their a solution on the back end?
Thanks all.
Josh

How about: lapply(Version1_, subset, subset=c(TRUE, FALSE)) or sapply() depending on what you want the result to look like. Thanks for the reproducible example.
