Hello list.

Until last week, I've been using my function without a problem. I can only
imagine what has changed (no package updates), but all of a sudden, a custom
function that uses raster::xyValues stopped working. For some reason, one of
the values is not found, even though it's there. Here is a snippet of code
from browser() call from within my custom function where everything goes
awry.

Browse[1]> effect.distance
[1] 220.2045  # just to make sure effect.distance is there
Browse[1]> unlist(xyValues(object = object, xy = origin.point, buffer =
effect.distance))
Error in .local(object, xy, ...) : object 'effect.distance' not found
Browse[1]> traceback()
2: stop(gettextf("no function '%s' could be found", f), domain = NA)
1: getS3method("xyValues", "method")
Browse[1]> environment()
<environment: 0x137d2b14>
Browse[1]> Q
> environment()
<environment: R_GlobalEnv>
> effect.distance
Error: object 'effect.distance' not found


If I call the unlist(...) line in R_GlobalEnv, it seems to work fine. I'm
wondering why this behavior?

Cheers,
Roman
