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?
