Trimming in R
I am looking for a way to trim leading and trailing spaces in a character
string in R. For example:
" this is random text "
should become:
"this is random text".
I have a short function to perform this task as follows:
trim <- function(str){
str <- sub("^ +", "", str)
str <- sub(" +$", "", str)
}

Subsetting Lists
I am looking for a way to create a vector which contains the second element of
every vector in the list. However, not every vector has two components, so I
need to generate an NA for those missing. For example, I have created the
following list:
lst <- list(c("a", "b"), c("c"), c("d", "e"), c("f", "g"))
> lst
[[1]]

Loading Rdata files in a Package
I have an .Rdata file saved in my "data" folder in a package I created. However,
when I use the data() function it doesn't recognize that there any dataset
exists within the package. Is there anything specific I need to do such that the
data() function will load my dataset?
Thanks in advance,
Andrew
