Hi...
I have a dataframe with n columns and n rows. I need to find how many rows
contains zero raw read count across all column.
(1) You should probably have a *matrix*, not a data frame.
(2) Have you ever heard of the idea of providing a *reproducible* example?
(3) I *think* the following may be what you want/need:
M <- as.matrix(M) # Where the initial M is your "data frame".
sum(apply(M,1,function(x){isTRUE(all.equal(x,rep(0,length(x))))}))
Untested, since you did not supply a reproducible example.
cheers,
Rolf
