Converting Grid to factor list
Edzer Many thanks. The grid was created in ArcView and exported as an ascii file. I then read it in R using the read.asciigrid function in map tools Any ideas? Ronnie

Ronnie, you didn't tell us how you created the grid. Is it on of the grid classes in package sp? In that case you can address the variable in it by it's name, say foo: mygrid.f <- factor(mygrid$foo) hth, -- Edzer Ronnie Babigumira wrote:
Hi listers I would like to change a grid to a factor list so as to apply Join Count statistics however when I use mygrid.f <- factor(mygrid) I get an error message " 'x' must be atomic". Looking through the RHelp archives, I have chanced on emails with a similar problem but no direct answer to this. Is anyone farmiliar with this and how can I go about it Many thanks Ronnie
