Hi Monica,
Try
sapply(as.list(str),function(x) unlist(strsplit(x,"
"))[1])

each string made up by different number of words. I want to get a new vector
which has only the first word of each string in the first vector. I came up

You need to define 'word' and 'first'. Your solution says the first word
of " aa" is "", which is not what most people would think.

Good afternoon Monica,
Relying on regular expressions, substituting nothing "" for everything
starting with a space until the end of the "line" (i.e. with a dollar sign)
str1 <- sub(" .*$", "", str)

Hi,
if you only want the first word, then this should do the trick :
R> sub( " +.*", "", str )
[1] "aaa" "cc" "d" "mmm"

Hi everyone,
I have a vector of strings, each string made up by different number of words. I
want to get a new vector which has only the first word of each string in the
first vector. I came up with this:
str <- c('aaa bbb', 'cc', 'd eee aa', 'mmm o n')
str1 <- rep(1, length(str))
for (i in
8 matches
