Dear users,

Is anyone out there on a Saturday to answer this easy question?

I have the "yo" object data in a "list" format:

> str(yo)
 num [1:259, 1:173] 16.3 NA NA NA NA ...
 - attr(*, "dimnames")=List of 2
  ..$ x: chr [1:259] "367319" "367329" "367309" "367339" ...
  ..$ y: chr [1:173] "780175" "780185" "780195" "780205" ...
> length(yo)
[1] 44807

where x is the name of the rows and y the name of the columns (coordinates)
of a matrix of 44807 values

how can I get a data.frame with these three columns: x, y, values

Many thanks to the Saturday working people.

Javier
