#I want to remove '_alpha' in a vector of strings myInput = c( "afg3_alpha", "alg12_alpha", "dbp3_alpha", "elp4_alpha", "fob1_alpha", "gpr1_alpha")
#my current solution tmpsplit = strsplit(myInput, '_') tmp = NA for (item in tmpsplit){ tmp = c(tmp, item[1]) } results1 = tmp[-1]; #this is what I need, but I want a better solution. #Here is what I come up with, but it is pretty awkward tmp3 = lapply(myInput, FUN=function(x){strsplit(x, '_')[[1]][1]}) results2 = unlist(tmp3) #Please help me revise the above loop.
