Problem with intersection between two different tables

Hi,


I'm a beginner with R.


I have two different? tables with
the variable name dmr1 and tp2 a given following. v1 is the common? column? field of
the both tables. In the first table column v3 is always v2+1 while in
the second table v2 and v3 hold the range. I want to know which rows
of tb1 intersect with the range between v2 and v3 of tb3. I need some one's kind help to solve this problem.

Hi.

The same question was asked a few hours before. If you
are not subscribed to R-help, then use the web interface

  https://stat.ethz.ch/pipermail/r-help/2011-January/thread.html

to search the messages with subject

  [R] how to search to value to another table 

There is a reply, which tests the intervals [a, b] from tb1 for
being a subset of [c, d] in tb2. If you need to test a nonempty
intersection, it is slightly more complicated, but not much.

Are you from the same research team?
