[R] R - how to measure the distance?

[porzycka at agh.edu.pl]

Hello,
I have been worked with R for 3 weeks. I have one problem. I could not
find the answer on it on web pages. I do not know how to measure the
shortes distance between point (Lon/Lat) and line. I used spatstat package
and distmap() but I want to calculate these distances only for particular
points without generate distance map.

Thank you for all hints.
