Directory location where the file should be written
filename
Name for the output file in the OS; .pop will be added.
userownames
If TRUE, will write the row names into the file.
Details
Writes the input data frame to the OS, using the .pop extension. Contents of the data
frame should be only what you want SaTScan to see.
This is a simple function that calls write.table, since SaTScan just needs ASCII files.
