I have a R list of strings and I want to get the last element of each
require(stringr)
string_thing <- "I_AM_STRING"
Split <- str_split(string_thing, "_")
Split[[1]][length(Split[[1]])]
but how can I do this with a list of strings?
require(stringr)
string_thing <- c("I_AM_STRING", "I_AM_ALSO_STRING_THING")
Split <- str_split(string_thing, "_")
#desired result
answer <- c("STRING", "THING")
Thanks
We can loop through the list
with sapply
and get the 'n' number of last elements with tail
sapply(Split, tail, 1)
#[1] "STRING" "STRING"
If there is only a single string, then do use [[
to convert list
to vector
and get the last element with tail
tail(Split[[1]], 1)
