Hi all,

I used the "replicate" function to make 2 samples from file "test" with 5 records in each sample and saved the output in "result".

result=replicate(2,test[,sample(colnames(test),5,replace =FALSE)],simplify=FALSE)

now I need to calculate the mean of each cell; i.e. I need to add "the number in cell 1&1 from sample 1" and "the number in cell 1&1 in sample 2" and divide it by 2. and do the same for all numbers in two sample( adding the number in cell 1&2 from sample 1" and "the number in cell 1&2 in sample 2",.......)

does anyone have any idea how to do it?
