Also possible is a Method that also works for very large rasters
(calculation done in chunks)<br>
<br>
C<-overlay(A, B, fun=function(a,b) return(a==b))<br>

<pre wrap="">Dear Gianni,
Something along these lines should directly return what you look for:
C <- A == B

<pre wrap="">Dear Members list,
I have two raster (A and B) with the same extent, number of rows and
columns, projection, resolution, and origin. Some pixels of A have the same
values of B.
I wish in a code saving style compare A with B and create a new raster
where the pixel value is 1 (when the statement is true: the pixel value of
A and B are equal) otherwise 0 (false)
Do you know some specific function in raster
Thanks in advance
Gianni
