...= 1) Every time a vector has been generated I would like to export it into a csv file. So my idea is something as follows: for (i in 1:100) { z <- rlnorm(1000, meanlog = 0, sdlog = 1) write.csv(z, "c:/z_i.csv") Where "z_i.csv" is a filename that is related to the run (e.g. z_001.csv, z_002.csv, ...). Could anyone please advice me on the most convenient way of doing this? Thanks very much in advance, Michael [[alternative HTML version deleted]]
