I have noticed that z values of a raster brick get lost when that brick is cropped using the 'crop' function in the raster package. I am running R 3.0.1 64 bit on Windows 7 and raster package 2.1-38. The example below illustrates the issue.
require(raster) r <- raster(nrow=45, ncol=90);r[]<-rnorm(45*90) r<-brick(r,r,r) r<-setZ(r,as.Date(c("2001-01-01","2001-01-02","2001-01-03"))) r.cropped <- crop(r,extent(-90,90,-10,10)) getZ(r) getZ(r.cropped) [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
