[R] re placePatterns() for multiple words replacement in tm
Hi all, I wonder how you can replace all words that need to be changed using replacePatterns(). The following is my code. I want to replace both "abc" and "def" to " Yes ". However, I can only replace the first occurrence in sample[[1]].> sample[[1]][1] abc def ghi> change <- c("abc","def") > replacePatterns(sample[[1]],change," Yes ")[1] Yes def ghi Thank you so much!!!! -- View this message in context: http://www.nabble.com/replacePatterns%28%29-for-multiple-words-replacement-in-tm-tp24921281p24921281.html Sent from the R help mailing list archive at Nabble.com.

Don't use replacePatterns() (-- and what package is that from, btw??).
gsub("abc|def","Yes",sample[[1]])
Incidentally, "sample" is a rather bad name for your dataset, as it is
the
name of a commonly use R function. Ergo, possibility of confusion.

Hi all,
I wonder how you can replace all words that need to be changed using
replacePatterns(). The following is my code. I want to replace both
"abc"
and "def" to " Yes ". However, I can only replace the first
occurrence in
sample[[1]].
> sample[[1]]
[1] abc def ghi> change <- c("abc","def")
> replacePatterns(sample[[1]],change," Yes ")
[1] Yes def ghi
Thank you so much!!!!
