Hi all, Anyone out there using Hawthorne's Geospatial Modelling Environment (Version 0.7.2.1). (software). URL: http://www.spatialecology.com/gme?
He has a set of examples for running iterations for running the same GIS data extractions using a loop. The example given is for kernel density estimates based on a set of input points. This uses R paste commands for inpath and outpath and defines the variable for the iterations Where the i = animal IDs and the j = months inpath <- "C:\data\" outpath <- "C:\output\" for (i in 1001:1010) { for (j in 1:12) { kde(in=paste(inpath, "telemetry.shp"), out=paste(outpath, "kde_an", i, "_m", j, ".img"), bandwidth=1000, cellsize=r.eval((250000-120000)/2000), where=paste("ANIMALID=", i, " AND MONTH=", j)); }; }; What I am trying is to generate Minimum Convex polygons using this code below. i= bat ID and j= survey night for radio tracking. inpath <-" Z:\_MCP\Feb_bats\Stonehouse\" outpath <-" Z:\_MCP\Feb_MCP_by_bat\Stonehouse\" for (i in 1:19) { for (j in 1:22) { genmcp(in=paste(inpath," Stonehouse_nights.shp"), out=paste(outpath,"MCP_Bat", i, "_night", j, ), where=paste("Bat=", i, " AND Night=", j));};}; I continue to get the following error message: +++++++++++++ Error: The default input/output working folders have not been specified, therefore not enough information has been supplied to open the specified data source Error: Could not open input point data source. +++++++++++++++++ Apparently I am blind, senile or both as it appears the in and out paths are defined. Hopefully a fresh set of eyes will spot the issue.
