I'm attempting to open a shapefile in R using rgdal. my code is simply:
shp <- readOGR("D:/Documents/EPA/Groundwater_Wells/R Work", "us_blocks_2010")
The error message I receive is:
Error: C stack usage 81982167 is too close to the limit
The shapefile I'm attempting to open is 2.09 GB. I am working with 32 GB of RAM on a 64 bit version of windows 10 and using R Studio 64 bit so this size should not be an issue according to (https://stat.ethz.ch/R-manual/R-devel/library/base/html/Memory-limits.html). This is a really large polygon dataset with about 11 million polygons representing all Census blocks in the United States. My question is: Is there a way to manipulate the maximum size that my R session can handle? or, is there a format, such as converting to a geopackage that will allow me to more efficiently use this data? Ultimately I would like to be able to convert it back into a format usable with ArcGIS such as a geodatabase but if I can work with the data more efficiently in a different format that only works in R, that's fine too.
Any help would be greatly appreciated!
