How to find maximum value in rasterbrick?

Question

I know there is a similar question but it is not in rasterbrick. I would like to find the maximum value in this raster brick, I tried which.max but I don't understand the input. I would like to know what is the maximum value, and also get a list of all the maximum values for each layer.

Answer 1

This is how you can get these:

library(raster)
b <- brick(system.file("external/rlogo.grd", package="raster"))
minValue(b)
# [1] 0 0 0
maxValue(b)
# [1] 255 255 255
