Suppose I have a data array,

dat <- array(NA, c(115,45,10))

How can I get a new data array

dat1<- array(NA, c(115,45)) by averaging dat by the third dimension?

Thanks

Try this:

dat1 <- apply( dat, c(1,2), mean )

the c(1,2) means keep the 1st and 2nd dimensions and apply the function (mean) over the rest (3rd).
