Hello list,

I used to be able to apply the function contourLines2SLDF for the 
following operation on a SpatialGridDataFrame object. 

> CL <- contourLines2SLDF(contourLines(as.image.SpatialGridDataFrame
+       (as(ht.idw["var1.pred"],"SpatialGridDataFrame"))))


The last time I ran this function successfully was in version 2.3.1. After 
upgrading to version 2.4.1 the function seems to have disappeared and I 
get the following message. 

Error: could not find function "contourLines2SLDF"

Is the function no longer compatible with the upgraded sp package?

Cheers

Karl
