r.mapcalc follows C expression syntax; "="is assignment, "==" is the
equality test.
In this case shouldn't it be
,----
| r.mapcalc down_id = if(dir==1, id[1,1], if(dir==2, id[0,1], if(dir==3,
id[-1,1] .... etc
`----
with "==" after the dir?
Yes, that's what Glynn is saying. Sorry, I wrote this example too quickly.
