ravi_...@yahoo.com
lavk....@rediff.com
xy@12_g.com",sep="",header=TRUE,stringsAsFactors=FALSE)
vec1 <-
gsub("\\.[[:alnum:]]+$","",gsub("^([[:alpha:]]+)(\\d+.*)","\\1_\\2",dat$Emails))
indx1 <- grep("[[:punct:]]+",gsub("\\@.*","",vec1))
res <- setNames(cbind(dat,do.call(rbind,lapply(seq_along(vec1),function(i) if(i
%in% indx1){strsplit(vec1[i],"[_@.]")[[1]]} else
strsplit(gsub("(.*)(\\@.*)","\\1*\\2",vec1[i]),"[*@]")[[1]]))),c("Emails","f.name","l.name","domain"))
res[sapply(res,is.factor)] <- lapply(res[sapply(res,is.factor)],as.character)
res
