Hi Henrique and Erik
I still get a error. See below.
apply(veh_drg_animal1[ ,c("readCount","gene_length")] ,1, stats,
total=55000000)
Error in FUN(newX[, i], ...) :
element 1 is empty;
the part of the args list of '(' being evaluated was:
(length_gene)
stats<- function(count,length_gene,total) {
( count/( total * (length_gene ) ) ) * ( 10^9)
}
Thanks!
