testpoints_block2010 R Documentation
Get lat lon for random US census blocks (where avg person lives or other weighting)
Description
Note the 2010 version of this is not optimized for speed- it can take 30 seconds to pick just 1,000 points if pop wtd.
May recode this to allow wts to be pop (using blocks.pop), or area (using blocks.area), or none (no weight).
Usage
testpoints_block2010(size, popwtd = TRUE)
Arguments
size
number of unique test points needed (no duplicates will be returned)
popwtd
default is TRUE, and pop weighted block points represent where the avg US resident lives.
If FALSE, unweighted, so each block has equal chance of being selected.
Details
This is probably obsolete at this point.
Value
data.frame with columns lon and lat, in decimal degrees
