[R-sig-Geo] how to read CRU climatic data files with R?

[Nicolas Degallier]

Hi R helpers,

I have downloaded time series of climatic data from CRU (Climatic  
Research Unit) which are ASCII files with a specific format for the  
data.
The format is described here:

http://www.cru.uea.ac.uk/~timm/grid/CRU_TS_2_1.html

under the link "file format".

I would like to know if somebody has already written some script in R  
to open and manage these data, for example for selecting only  
portions of the time series and/or pieces of the spatial grid?

Cheers,

Nicolas Degallier
