FAQ spcosa-package

---------------------------------------------------------------------

Q: The stratify-method returns a cryptic error. What is going
wrong?

A: You probably don't have the most recent version of Java
installed. Java is freely available at www.java.com

Q: The stratify-method returns the following error message:
'Error: strata of equal area in combination with map
projections are currently not supported'. What solutions are
available?

A: Stratification for maps with projection attributes is
currently not supported. If the area of interest is relatively
small (e.g. a field), it is quite safe to ignore projection
attributes. This can be accomplished by calling the
proj4string-function of the sp-package:

proj4string(myMap) <- NA_character_

You have to call 'proj4string' prior to stratification.

Q: I can't find a MacOS X binary on CRAN for the
spcosa-package. Why is that?

A: spcosa depends on the rgdal-package. Unfortunately, this
package is not available for MacOS X. You may try to build it
from sources yourself.
