Right. You forgot the comma!

When I changed && with & I got this error:
new <- intra[(intra$start != intra$region_start )&(intra$end !=
intra$region_end)]
Error in `[.data.frame`(intra, (intra$start != intra$region_start) &
(intra$end != :
undefined columns selected
What I would like to do is to create a new table that only contains
the rows
for which column start and region_start are not the same.
