nc.imtx: Index matrix for NetCDF
In CJBarry/DRW: Dynamic Random Walk
Description
Usage
Arguments
Value
Description
Emulate the A[B] matrix indexing behaviour in R for NetCDF
connections whilst avoiding reading large arrays into memory.
Usage
1
nc.imtx(ncfile, variable, imtx)
Arguments
ncfile
NetCDF object (see open.nc)
variable
character string; the variable name in the NetCDF file
imtx
integer matrix;
the indices to read; must have the same number of columns as variable
has dimensions; must contain only positive integers and no NAs; ideally
the range of values in some or most columns would not be very large to
avoid reading a large array into working memory
Value
a vector whose type corresponds to that of variable
