Re: [R] Making objects global in a package

I would usually use a function for this. It may not be more R like, but it is more readable to me. If you want, to keep the columns in a file, you could have the function initialize itself on the first call. Mark R. Mark Sharp, Ph.D. Data Scientist and Biomedical Statistical Consultant 7526

Marco, The error message indicates that nlon*nlat is 420 and that 1378620/420 has a remainder. For the matrix to form, all rows have to be complete. I am guessing you have at least one value incorrect among nlon, nlat, t or the length of fulldatav. Mark R. Mark Sharp, Ph.D. Data Scientist
