I´m getting the following error when trying to convert a spatial lines
object into a raster using the rasterize function (package raster):

Slot "lines":

An object of class "Lines"
Slot "Lines":
[[1]]
An object of class "Line"

Ahhh...a missing "+". Probably caused by a lack of caffeine. :)
Thanks also for suggesting the raster package... I will look into this.

Also the "PBSmapping" package is a very good alternative to make maps
within R, and to perform basic GIS operations (i.e. overlap of poly

large dataset (~25 rows) consisting of lat, long and a data value.
The data has been collected in a regular grid, but the grid is
"tilted". In other words, along a row the latitude values increase
constantly,
n't find a package with this
functionality), and I would be happy to pass it along. My function wasn't
extremely efficient but worked well enough to process thousand of matrices (each
100x100) in a relatively short time. Let me know if you need it.
