This function is intended for use by
make.cdf.env
, which in turn is called by
make.cdf.package
. User may not have much
benefit from calling this function directly.
In order to save memory, the name corresponding to each value in the
CEL is a factor. As in R factor
objects
cannot be also of type matrix
, the names corresponding to the indices
were stored in a vector of type character
called
name.levels
.
The same thing was done with the pbase and cbase information (more for
consistency than by conviction that some memory
could be saved here).
Returns a Cdf-class
object.
