I am working with a large data set of arrivals, for each day I have aggregated the arrivals into hrs (1-24) via: apply(x,2,table). On some days there are zero arrivals during some hours of the day, this leaves me with (I believe) a list of vectors of differnt lengths (see below).
[[4]] 1 2 3 5 6 8 9 10 11 13 14 15 16 17 18 19 20 21 22 23 24 1 3 2 3 1 1 2 3 4 4 4 3 2 6 2 5 1 2 2 2 1 [[5]] 2 5 6 8 9 10 11 12 13 14 15 16 17 18 19 20 22 23 24 2 1 1 2 1 5 3 6 6 3 2 2 1 4 3 3 4 2 1 I would like to be able to create an array with equal numbers of rows (24) for each column, i.e., fill in the gaps with Zeros.
