I wanted to print the first and last rows of some dataframes in Sweave
using dots in columns to separate the two parts. Head and tail almost
work, but I have problems with factors and row names.
z<-data.frame(id=letters[1:26], x=sample(1:26,26))
rbind(head(z,3), ".", tail(z,1))
id x
1 a 18
2 b 8
3 c 14
4 <NA> .
26 z 10
Warning message:
invalid factor level, NAs generated in...
I would like something like this if possible. Any ideas?
id x
1 a 18
2 b 8
3 c 14
. . .
. . .
26 z 10
Thanks,
Chris Stubben
