To put in more general,
C=c("My Dog", "Its really good", "Beautiful")
And the resultant output should be

To put it simple,
C=c("My Dog", "Its really good", "Beautiful")
Now,
SOMEFUNCTION(C) should give: c("My", "Its really",
"")

See strapply in the gsubfn package and the gsubfn home page at gsubfn.googlecode.com. Here we extract the words, the last word and all but the last word:> library(gsubfn) > strapply(C, "\\w+")[[1]] [1] "My" "Dog" [[2]] [1] "Its" "really" "good" [[3]] [1] "Beautiful"> sapply(strapply(C, "\\w+"), tail, 1)[1] "Dog" "good" "Beautiful"> sapply(strapply(C, "\\w+"), tail, -1)[[1]] [1] "Dog" [[2]] [1] "really" "good" [[3]] character(0) On Wed, Apr 9, 2008 at 11:44 AM, Shubha Vishwanath Karanth <shubhak at ambaresearch.com> wrote:> Got all the answers using ?strsplit...

Actually the last example was all but the first word, not all but the last word. All but the last word is:> sapply(strapply(C, "\\w+"), head, -1)[[1]] [1] "My" [[2]] [1] "Its" "really" [[3]] character(0) On Wed, Apr 9, 2008 at 11:56 AM, Gabor Grothendieck <ggrothendieck at gmail.com> wrote:> See strapply in the gsubfn package and the gsubfn home page at > gsubfn.googlecode.com. > Here we extract the words, the last word and all but the last word: > > > library(gsubfn) > > strapply(C, "\\w+") > [[1]] > [1] "My" "Dog" > > [[2]] > [1] "Its" "really" "good" > > [[3]] > [1] "Beautiful" > > > sapply(strapply(C, "\\w+"), tail, 1) > [1] "Dog" "good" "Beautiful" > > sapply(strapply(C, "\\w+"), tail, -1) > [[1]] > [1] "Dog" > > [[2]] > [1] "really" "good" > > [[3]] > character(0) > > > > On Wed, Apr 9, 2008 at 11:44 AM, Shubha Vishwanath Karanth > <shubhak at ambaresearch.com> wrote: > > Got all the answers using ?strsplit...
