[R] distances from points to line

Dear all,

I have discovered that there are many things that I used to do in my GIS
which are easily done directly in R, for example calculating interpoint
distances using geoR and pick out points inside a polygon using splancs.

I now wonder, is there a function to create a line object like a
watercourse and then calculate the distances between many points in space
and this line?

I couldn't find it in geoR, splancs, spatial or RArcInfo.

Thanks in advance!


Sincerely,
Tord Snäll
