Hi,
If you want to just count the words in R, try this:
vec1<-c("uno dos tres", "cuatro cinco", "seis")
#get individual word count within quotes
res1<-unlist(lapply(strsplit(vec1, " "),length))
res1
#[1] 3 2 1
#get whole word count
length(unlist(strsplit(vec1, " ")))
#[1] 6

Subject: [R] Trying to use pipes in R
Hi,
I'm trying to use pipes in R. By now, I could launch the linux command "wc"
(to count words from a text), but
I don't know how to capture the results, say in a vector of chars...
Here is the R code I'm trying:
:> f <- pipe("wc", open="w")
:> writeLines(c("uno dos tres", "cuatro cinco", "seis"), f)
:> close(f)
: 3 6 31
The result is just displayed but I couldn't put the result into a R
variable.
Do you have any comments on this?
Thanks,
-- Sergio.
