Write a function that calculates the sample means for a vector of 95
observations and then use apply() to apply that function to the whole

Thanks. But aggregate will work on rows or columns. I need to calculate mean
for subsets of rows in a matrix
I.E.
Indx x1
l(res1)]<-i}
res1}
fun1(dat1,ids)
# 1 2 3
#[1,] 23.3 9.67 42.7
#[2,] 43.0 53.00 24.0
#[3,] 26.7 50.67 27.3
#[4,] 22.0 44.33 28.0

Dear List,
I have a data matrix with 570 columns containing 95 (samples) with 6 replicates
each.
How can I calculate the mean of the replicates for 95 samples?
Thank you.
