[R] R version of MATLAB interpn?

[Steven M. Matz]

Is there an existing R function to perform n-dimensional linear
interpolation, like MATLAB's interpn (
http://www.mathworks.com/help/matlab/ref/interpn.html; a Python version is
here: https://github.com/scipy/scipy/issues/2246#issuecomment-17028264)? My
searches didn't turn up anything.

Maybe not terribly difficult to implement, but I didn't want to reinvent
the wheel...


Thanks,
Steven Matz
