R-help,
I want to remove the following strings
"cpue" and "nogd"
string <- c("upsanogd" , "toskanogd" ,
"hysunogd" , "konganogd"
,"gullaksnogd" , "longunogd" , "blalongunogd"
, "brosmunogd")
I could use first : first <- gsub("cpue" , "", string)
and then : second <- gsub("nogd" , "", first)
Can it be done at once?
Thanks in advance

For example, abba|cde matches either the string abba or the string cde. Note that alternation does not work inside character classes, where | has its literal meaning." Duncan Murdoch
Is this what you want? :
gsub("cpue\|nogd", "", string)
