Hello, from a vector of strings I want to delete everything after the _
v <- c("AAA_BB", "FF_MM")
gsub("_*", "", v)
[1] "AAABB" "FFMM" but should be [1] "AAA" "FF" Why does * not work? Even perl=TRUE does not give me the right result Man thanks! -- View this message in context: http://r.789695.n4.nabble.com/gsub-to-manipulate-characters-tp4416939p4416939.html Sent from the R help mailing list archive at Nabble.com.
