Dear R helpers I have following input f = c(257, 520, 110). I need to generate a decreasing sequence (decreasing by 100) which will give me an input (in a tabular form) like 257, 157, 57 520, 420, 320, 220, 120, 20 110, 10 I tried the following R code f = c(257, 520, 110) yy = matrix(data = NA, nrow = 3, ncol = 6) for (i in 1:3) { value = NULL for (j in 1 : 6) { value = c(ans, seq(f[i], 1, by = -100)) } yy[i,] = ans[i,j] } I get following message Error in ans[i, j] : incorrect number of dimensions. Also, I understand above logic will generate a result in (3 by 6) matrix format, while I need to generate only 3 numbers pertaining to first no. i.e. 257, 6 nos. beginning from 520, and only 2 numbers beginning from 110. I also tried tapply etc. Please guide Vincy [[alternative HTML version deleted]]
