Hi everyone, I'm trying to use the acf() function to calculate the autocorrelation of each column in a matrix. The trouble is that I can only seem to get the function to work if I extract the data in the column into a separate matrix and then apply the acf() function to this column.
I have something like this: acf(mat,lag.max=10,na.action=na.pass) ...but I would really like to apply the function to 'mat' where 'mat' is a matrix as opposed to a vector. The function actually doesn't return an acf coefficient, but instead plots the data. So, in addition to handling matrices with multiple columns, would anyone know how to coerce the function to output the underlying data? Finally, when working with a matrix, is there a way I can specify how many plots I can display after the function executes? I managed to generate a multiple plot when I was experimenting, but the titles suggested the acf was calculated between adjacent columns in the matrix, which is something I was puzzled about.
