[R] convert binary vector to time series of sum(x)/minute

Dear members, I apologize for the relatively simple request, but I couldn't find exactly what I was looking for. I have a binary vector [1,0] representing presence/absence at 1 second intervals over length(N). I would like to convert this to a new time series vector with N/60 elements that

Hi mac, Try N - 6000 x - sample(1:0, N, TRUE) tapply(x, rep(1:(N/60), each = 60), sum) HTH, Jorge On Sat, May 21, 2011 at 1:59 PM, andyjmac wrote: Dear members, I apologize for the relatively simple request, but I couldn't find exactly what I was looking for. I have a binary vector
