Thanks so much! it works fine!
But when I convert the result to a data frame, it mess up.
so i have:
res <- data.frame(res)
then i get:
X1 X2 X3
That is very helpful Rui, thanks so much!

Hello,
You should provide us with a data example, like the posting guide asks
you to.
Without one, you could adapt the following example to your case
# Make up some data
dat <- data.frame(X = rnorm(200), Y = rnorm(200))
# Divide into subsets of 60 rows each and compute the col means
grp <- r

I have a large dataset and I want to calculate the average of each column
then return a new dataset.
Here is my question: I dont know if there is a function that can allow me
to calculate the average every 60 records of data in the whole dataset, and
return a new data frame. Not sure if
7 matches
