´╗┐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
