Steve, I think you can use:
write.table(x, file = "/Users/Desktop/Data.txt", sep = "", append=T, row.names = F, col.names = F) I used that for the data PERSHRUB DISTX AGE RODENTSP 1 66 2100 50 1 2 90 914 20 1 3 75 1676 34 1 4 75 243 34 1 5 60 822 16 1 6 50 121 14 1 7 5 1554 79 0 8 20 1219 58 0 9 30 2865 36 0 10 52 670 31 0 and got 662100501 90914201 751676341 75243341 60822161 50121141 51554790 201219580 302865360 52670310 Hope this helps, Bob On Fri, 2008-05-02 at 18:02 -0700, Stropharia wrote: > Dear R users, > > I've had no joy finding a solution to this online or in any of my R books. > Many thanks in advance for any help you can give. > > I'm seeking to output a data frame (or matrix - it doesn't matter which for > my purposes) to a .txt file, but omit any row or column names.
