I'm trying to teach myself R and in doing some sample problems I came across the need to reverse a string.
Here's what I've tried so far but the paste operation doesn't seem to have any effect.
There must be something I'm not understanding about lists? (I also don't understand why I need the [[1]] after strsplit.)
> test <- strsplit("greg", NULL)[[1]]
> test
[1] "g" "r" "e" "g"
> test_rev <- rev(test)
> test_rev
[1] "g" "e" "r" "g"
> paste(test_rev)
[1] "g" "e" "r" "g"
