Hello,
Your matrix has only 4 columns but you refer to met[,5]. I'll assume
you're refering to the last column, met[,4]. Try reading the help page
for ?%in%, it doesn't do what you seem to think it does. And try using <=.
maf <- met[0 <= met[, 4] & met[, 4] <= 0.05, ]
Hope this helps,

I want to choose a subset from "met" which maf values are between 0 and
0.05 (0,0.05)
I wrote this code, but seem doesn't work properly:
maf<- met[which(c(met[,5]) %in% c(0,0.05)),]
the dim(maf) is 0 so seems my code didn't work!
would please let me know how to correct it?
Thanks
