Hi.
I have a 4 layered raster brick of rainfall totals, and want to create a raster
brick of rainfall total ranks (so at any x,y coordinate, the cell values down
through the brick will be some permutation of 1,2,3 and 4 (assuming no ties)).
There are no NA values in the data.
The brick is called temp
> temp
class : RasterBrick
dimensions : 400, 324, 129600, 4 (nrow, ncol, ncell, nlayers)
resolution : 0.05, 0.05 (x, y)
extent : 137.525, 153.725, -29.975, -9.975 (xmin, xmax, ymin, ymax)
coord. ref. : NA
data source : in memory
names : r198612, r198701, r198702, r198703
min values : 0, 0, 0, 0
max values : 320.8333, 428.2410, 922.9112, 632.9712
However when I use the stackApply function, I get the following error
> stackApply(temp, indices=c(1,2,3,4), fun=rank)
Error in FUN(newX[, i], ...) : unused argument (na.rm = TRUE)
Many thanks for any help.
