Description
A function to extract anomalies from the Climatic Research Unit Time-Series dataset
Usage
1
2
Arguments
ncfile
character string giving name and location of the CRUTS time series NetCDF file (if the file you downloaded is zipped, then you will need to extract it)
poly
an optional SpatialPolygonsDataFrame on which to compute the average anomalies if NULL (the default) a raster brick will be returned
timeRange
vector of length 2 giving the start and end dates in the first and second place. Dates are converted using the function ymd, please refer to the help for this funciton for details on appropriate formats.
offset
time offset for CRU TS data
na.rm
logical, whether to ignore NA's in averaging, default is FALSE (to be consistent with other R functions in other packages), but option TRUE should probably be used on most occasions
Details
Data can be obtained from http://catalogue.ceda.ac.uk/uuid/ac4ecbd554d0dd52a9b575d9666dc42d
