names.tensor: Getting and setting index and dimensionnames of a tensor
Description
The names of a tensor are the names of its dimension
Usage
# S3 method for tensor
names(x)
# S3 method for tensor
names(x) <- value
# S3 method for tensor
dimnames(x)
# S3 method for tensor
dimnames(x) <- value
# S3 method for tensor
dim(x) <- value
Value
the names of the dimensions the tensor
Arguments
x
a tensor object
value
The new value. If this is a named list it replaces the
names of the dimensions. If its an unnamed list it gets the names of
the dimensions.

Details
The names of the dimensions of the tensor are very relevant in any
tensor arithmetic since they are the principle way to specify the
dimensions to be involved in an operation. The dimnames function is
here only for convenice to guarantee that the names of the dimnames are
always the same as the names of the dimensions and to ensure that
always at least a list with the right length and names.
