I try to remove numbers from text without using tm_map :
# remove grammar/punctuation and numbers
Data_clean$Raison.Reco.clean <- tolower(gsub('[[:punct:]]', '', Data_clean$Raison.Reco))
Any idea please?
Thank you

Please provide example input text and expected output. – zx8754 Apr 27 '17 at 12:47

This will replace all digits (`\d`) with "" in column `x` of your data frame... `gsub("\\d","",df$x)` – Andrew Gustar Apr 27 '17 at 12:52

Ok thank you, `Data_clean$Raison.Reco.clean <- tolower(gsub('[[:punct:]][0-9]+', '', Data_clean$Raison.Reco))` – dr.nasri84 Apr 27 '17 at 12:52

You might want `[[:punct:]0-9]` or `[[:punct:]\\d]` instead - your regex will look for a punctuation mark followed by a digit, rather than one or the other. – Andrew Gustar Apr 27 '17 at 12:55
