Subject: hist() in raster package
Hi!
I'm confused by the following
> r <- brick("SDIM0069.tif")
> nlayers(r)
[1] 3
Then I do
> hist(r)
and get 3 histograms plotted, but I do:
> a <- hist(r,plot=F)
and object a seems to hold the histogram of only one layer (actually,
the 3rd one):
> str(a)
List of 7
$ breaks : num [1:19] 0 5 10 15 20 25 30 35 40 45 ...
$ counts : int [1:18] 337 1131 1280 1172 951 815 808 827 741 636 ...
$ intensities: num [1:18] 0.00675 0.02264 0.02563 0.02346 0.01904 ...
$ density : num [1:18] 0.00675 0.02264 0.02563 0.02346 0.01904 ...
$ mids : num [1:18] 2.5 7.5 12.5 17.5 22.5 27.5 32.5 37.5 42.5 47.5 ...
$ xname : chr "values"
$ equidist : logi TRUE
- attr(*, "class")= chr "histogram"
Am I doing something wrong?
Thanks
Agus
PS. Is package RemoteSensing being under active development?
