Not sure where your problem is. If you have the SpatialPixelsDataFrame and
the SpatialPoints, did you try to go on like in the example?
tab <- slot(map, "data")
pr <- slot(count.points(locs, map), "data")[,1]
pc <- dudi.pca(tab, scannf = FALSE)
(enfa1 <- enfa(pc, pr, scannf = FALSE, nf = 3))
etc., etc.

Dear Mathieu,
The join/cbind/@data is wonderful!
However, if I try to join the location data as a data.frame or sp class it
does not work.
What would be the solution to this portion of the equation?
In other words, how to I add locations to the formula?
Thank you a million * ∞ !
Alannie
