I have been trying to work within the GRASS70 Command Line to interface with R. When I try to read in the rasters I get the following error:
In deleteDataset(DS) :
Failed to delete dataset: C:\Users\....\Desktop\grass_data\PERMANENT\.tmp\unknown\nomralized_height
I navigate to the .tmp file and delete the rasters manually but I still get the same warning.
I am noticing that the R grass interface runs R in 32 bit. Is there a command to run R in 64 bit.
I notice when I run the stand alone R 64bit and use the interface to grass command:
initGRASS("C:/Program Files (x86)/GRASS GIS 7.0.svn", gisDbase="C:/Users/brown782/Desktop",location="grass_data",mapset ="PERMANENT", override=T)
R will give aforementioned error but it does read the rasters and I can do a whole suite of summary statistics.
I still have not been able to get the Fuzzy K-mean to run because the EMCluster package requires the data to be in a matrix and when I do this I am getting some strange Dimensions in R.
Any advice would as always be much appreciated
Sincerely,
Robert Brown

have a look to http://grasswiki.osgeo.org/wiki/R_statistics#GRASS_7_Usage
In WinGRASS 7 (standalone installer) the Windows batchfiles for use with R
are now integrated for a smooth WinGRASS-R-integration. The
R-installation-path is dynamically loaded into PATH.
Start WinGRASS 7, bring the WinGRASS-windows console in front and type R for
opening a R-session (command line mode) inside a GRASS-session.
