Dear all, I am trying to run the codes of "greenbrown" package for detection in raster time serie. However the error below reported occurs. ##### library(greenbrown) data(ndvimap) ndvimap plot(ndvimap,8) # calculate trend: annual aggregation method AATmap <- TrendRaster(ndvimap$X1982.01.01, start=c(1982, 1), freq=12, method="AAT", breaks=1) Error in .calcTest(x[1:5], fun, na.rm, forcefun, forceapply) : cannot use this function ############ Could anyone help me to solve it? Thank you, Jackson

a) You had to go out of your way to even install this package... it is lonly available on R-forge. This kind of question seems likely to require support from the package author. (Use the"maintainer" function to identify the author.) b) You may find a similar functionality in a CRAN package. Try describing what you want to accomplish on the R-sig-geo mailing list.
