I am afraid I am quite new to spatial analysis at anything beyond a superficial level, and I have only recently transitioned to utilizing R. I have been quite pleased with the versatility of areal analysis, but I have just attempted to load my first point layer.
In a nutshell, it's taking much, much longer than anticipated. I first tried to use readShapeSpatial (from maptools I believe), but I read somewhere that readOGR (from rgdal) was faster. I let readShapeSpatial run for over an hour before killing it, and now readOGR has been running for at least 20 minutes.
Here is the line:
The data attribute houses a frame containing character and numeric data. There are 106,046 records and 46 columns. The file size is only ~75MB (including the all elements of the shapefile).
I do not believe my hardware is underpowered for this task (though I am always happy with more horsepower):
OS: Ubuntu 13.04 (VMWare) on Windows 7
Make/Model: Dell/OptiPlex 790
Processor: i3 (3.3 GHz)
RAM: 16 GB installed
I should mention that I have been able to successfully parse and display an XML document from within my IPython Notebook session that resides in the same directory. That suggests, to me, that reading from a mounted directory is not an issue.
Have I done something incorrectly here? R seems to just hang in the "Busy" status, both in RStudio and IPython Notebook (via %rmagic). How long should such a read in take?
