Hi, I am very new to R and I am trying to write KML files. I am running R-2.13.1 and I have the following packages:
- AKIMA - RGDAL - RSAGA - SP I was trying to run the simple example that I found at the following web page: http://spatial-analyst.net/wiki/index.php?title=Export_maps_to_GE The lines that I can run are: data(meuse.grid) coordinates(meuse.grid) <- ~x+y gridded(meuse.grid) <- TRUE proj4string(meuse.grid) = CRS("+init=epsg:28992") # raster to polygon conversion; writeGDAL(meuse.grid["soil"], "meuse_soil.sdat", "SAGA", mvFlag=-99999) rsaga.geoprocessor(lib="shapes_grid", module=6, param=list(GRID="meuse_soil.sgrd", POLYGONS="meuse_soil.shp", CLASS_ALL=1)) and it crashes there with the following error message: Error in setwd(env$workspace) : character argument expected In addition: Warning message: In rsaga.env() : SAGA command line program 'saga_cmd.exe' not found in any of the paths C:/Program Files/R/R-2.13.1/library/RSAGA/saga_vc C:/Program Files/R/R-2.13.1/library/RSAGA/SAGA-GIS ... Can someone please let me know what I should do to fix that error?
