I have a data set which looks like:
> data<-c( "IGHV1-2*02 F, or IGHV1-2*03 F","IGHV3-23*01 F, or
> IGHV3-23*04 F","IGHV2-70*01 F","IGHV7-4-1*01")
I would like to keep the first appearance of "V1-2" for example and delete anything which follows (including the "*").
So I tried the following:
> data.substr<-substr(data,4,9)
> data.substr1<-gsub("*","",data.substr)
but I still cant get rid of the "*", probably because it serves as a placeholder…
Does anyone have an idea?

put
*in square brackets, it will be treated as character, then any value.*until the end of the string$will be removed.
