| Add contours {GCDkit} | R Documentation | 
Superposes contour lines to a Figaro-compatible plot.
addContours(GUI = FALSE, bandwidth = "auto",...)
| GUI | logical; is the function called from GUI (or in a direct mode)? | 
| bandwidth | vector of bandwidths for x and y directions provided to the function  | 
| ... | additional parameters passed to the underlying function  | 
This is, in principle, a front end to the standard R function contour. It will work on both the 
stand-alone Figaro-compatible plot or a plate thereof. 
The  bandwidth should be a positive number or 'auto', whereby the higher value corresponds to a smoother result.
The necessary calculations are done by the function kde2d. 
None.
