How do I get the data for a particular blip?

• make sure the pointerinfo plugin is enabled
• move the cursor over the blip in the plot window
• record the sample and pulse numbers from the pop-up pointer info window
• use them as follows:

blip <- rss.patch.at.rc(sample, pulse)  ## This returns an n x 2 matrix of coordinates of the blip.
attr(blip, "is.blip")                   ## TRUE if the patch is a blip, FALSE if it is a non-blip patch
blip.raw <- RSS$scan.mat[blip]          ## return the vector of raw sample values for this blip
