Hi All,
I need to use the predict{gstat} function in one of my functions for a
R package. I use RStudio to make the package. When I specified
gstat::predict in the function, I received the following error:
Error: 'predict' is not an exported object from 'namespace:gstat'
gstat exports 'predict' as an S3method; if it would export 'predict' as
an object, this would hide the generic in package stats.
The solution to your problem is to not put prepend 'predict' with
gstat::, but instead rely on S3 method dispatch.
Is it possible that the OP is not importing correctly in the NAMESPACE
file of the package in question?

The actual, un-exported function called is gstat:::predict.gstat, but it
is discouraged to call that directly.
The session information is:

Is this a bug? Any suggestions? Many thanks in advance!
