system is computationally singular: reciprocal condition number
Hi folks,
I know, this is a fairly common question and I am really disappointed that I
could not find a solution.
I am trying to calculate Mahanalobis distances in a data frame, where I have
several hundreds groups and several hundreds of variables.
Whatever I do, however I subset it I get the "system is computationally
singular: reciprocal condition number" error.
I know what it means and I know what should be the problem, but there i...

Predict function in Raster package
Hey,
I am having troubles using the 'predict' function with in the Raster
package. I am using pm<-predict(mm, predictors) where mm is the
mahalanobis distance and the predictors are a stack of 6 raster layers
containing environmental variables.
When I try to run the prediction I get the following warning message:
Warning message:
