#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. Thanks, -- Hong
