Hello, 

I am attempting to manipulate strings in which there are differing amounts of 
whitespace before and after each element taht I want to keep (any word, letter, 
or number). However, after strsplit and unlist, I know how to select specific 
elements with "[ ]", but I want to select instead all elements that are not 
missing. That is, do not select any elements that are simply "". 

output <- c("a     b   8888      6")

gsub(" ","",unlist(strsplit(output,"  ",fixed=TRUE)))
[1] "a"    ""     "b"    "8888" ""     ""     "6"   

Thanks! Scott Chamberlain
