Finding distances between points and contour lines

rhodes.uor 
Hi all,

I have two sets of data; a dataframe of lon/lat pairs which correspond to
storm track locations, and a gridded rainfall dataset. I've taken contours
of the rainfall dataset at a single level and saved them as a
SpatialLinesDataFrame. I'm attempting to determine the distance between each
of the storm track coordinates and each of the contours. Below is an example
of what I have so far, but I can't figure out the next step:



For each entry in track.pts I want to return a distance to the nearest point
of each entry in contourSL (or in contours, for that matter). Can anyone
recommend a way to do this?
Thanks very much!
