Jennifer -
Does this do what you want?
v1 = sapply(output,'[[','vec')
v2 = sapply(output,'[[','other')
v1
[,1] [,2]
[1,] 1 6
[2,] 2 7
[3,] 3 8
[4,] 4 9
[5,] 5 10
v2
[1] "stuff" "stuff"
(in more readable form:
v1 = sapply(output,function(x)x$vec)
v2 = sapply(output,function(x)x$other) )
Notice that if the objects returned by sapply are not conformable,
it will return its result in a list.

Good evening
I often have as output from simulations a list of various values, vectors
and matrices.
Supposing that I then run said simulation several times, I often want to
extract a particular result from each simulation for plotting and,
ideally, put it in a matrix.
A simple example
v1 <- 1:5
v2 <- 6:10
other1 <- "stuff"
other2 <- "stuff"
set1 <- list(v1,other1)
names(set1) <- c("vec","other")
set2 <- list(v2,other2)
names(set2) <- c("vec","other")
output <- list(set1, set2)
Is there some form of lapply() that will allow me to extract v1 and v2
(ie, the $vec elements) from both sets?
Bonus if I can then put it into a matrix tidily.
many thanks
Jennifer Young
