[R-sig-Geo] Help with contour plots

[Cristina Silva]

Dear all,

I have a SpatialLinesDataFrame with bathymetric lines, built with:

cl <- 
ContourLines2SLDF(contourLines(as.image.SpatialGridDataFrame(prof.grid2["z"]), 
levels=c(50, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 2000, 
3000, 4000)))

This object has all the bathymetric lines. Is there any way to plot some 
of the lines using this object or do I have to build the SLDF with only 
the lines that I want to plot?

Regards,

Cristina
