When inserting single entries into a list list, you should use the '[[ ]]'
notation. Use '[ ]' when you want to extract multiple entries or copy
multiple entries from one list to another:
l <- list()
l[[ 1 ]] <- 5
l[[ 2 ]] <- 'cd'
l[[ 3 ]] <- matrix( 1:4, 2, 2 )
l
[[1]]
[1] 5
[[2]]
[1] "cd"
[[3]]
[,1] [,2]
[1,] 1 3
[2,] 2 4
Hope this helps!
