Directory location where the file should be written
filename
Name for the output file in the OS; .geo extension will be added.
userownames
If TRUE, will write the row names into the file.
Details
Writes the input data frame to a file in the OS, using the .geo 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.
