How can I get around memory problems in R? -


i'm applying function image(cp) gps data when throws following error

error in image(as(x, "spatialgriddataframe"), ...) :    error in evaluating argument 'x' in selecting method function 'image': error: cannot allocate vector of size 12.3 mb 

the spatialpointsdataframe of relocation gps data has 2 columns. 1 coordinates, other id of animal.

i'm running on 32 bit system 4 gigs of ram.

how around this?

one way might work no thinking required:

library(raster) r <- raster(cp) image(r) 

but, cp "gps data" it's not @ clear why imageable.

one thing can plot it:

plot(cp) 

that work spatialpointsdataframe. if want create image somehow you'll need specify details.
