Dear R helpers
Suppose
M <- c(1:10) # length(M) = 10
N <- c(25:50) # length(N) = 26
I wish to have an outut file giving M and N. So I have tried
write.csv(data.frame(M, N), 'output.csv', row.names = FALSE)
but I get the following error message
Error in data.frame(M, N) :
arguments imply differing number of rows: 10, 26
How do I modify my write.csv command to get my output in a single (csv) file
irrespective of lengths.
Plese Guide
Thanks in advance

If it is something else, write.csv() will try to make it a data frame. You may want to create the data frame like this: data.frame(M = c(M, rep(NA,length(N) - length(M))), N=N) M N 1 1 25 2 2 26 3 3 27 4 4 28 5 5 29 6 6 30 7 7 31 8 8 32 9 9 33 10 10 34 11 NA 35 12 NA 36 13 NA 37 14 NA 38 15 NA 39 16 NA 40 17 NA 41 18 NA 42 19 NA 43 20 NA 44 21 NA 45 22 NA 46 23 NA 47 24 NA 48 25 NA 49 26 NA 50> Plese Guide > > Thanks in advance > > Maithili > > > > The INTERNET now has a personality.

Hello,
maybe that helps:
write.csv(paste((c(m,rep(" ",length(N)-length(M)))),n,
sep=";"), "output.csv", row.names=F)
