[R] do the standard R analysis functions handle spatial "grid" data?

[chris howden]

Hi everyone,

I'm doing a resource function analysis with radio collared dingos and GIS
info.

The ecologist I'm working with wants to send me the data in a 'grid
format'...straight out of ARCVIEW GIS.

I want to model the data using a GLM and maybe a LOGISTIC model as well. And
I was planning on using the glm and logistic functions in R.


Now I'm pretty sure that these functions require the data to be in a 2-D
spreadsheet format. And for me to call the responses and predictors as
columns from a data.frame (or 2-D matrix)

However I'm being told they can handle the data in a 'grid' format. So I'm
pretty sure this would mean I would be calling the responses and predictors
as 2-d matrices...and I don't think these functions can do that?


Can anyone enlighten me?

Am I right in thinking these function cannot handle data in a 3-D 'grid'
format and require data to be entered as a 2-d data.frame or matrix?


Are there other special functions out there that can handle this type of
data, and I should be using these instead?

Thanks for your help
