st: New version of -xsvmat- on SSC

["Roger B. Newson" <r.newson@imperial.ac.uk>]

Thanks one more time to Kit Baum, a new version of the -xsvmat- package 
is now available for download from SSC. In Stata, use the -ssc- command 
to do this, or -adoupdate- if you already have an old version of -xsvmat-.
The -xsvmat- package is described as below on my website, and is an 
extended version of -svmat-. The new version adds an option 
-from(matrix_expression)-, specifying an alternative source for the 
input matrix, which can now be an arbitrary Stata matrix expression 
instead of an existing Stata matrix. For instance, in the Stata -auto- 
data, the user may type
regress mpg weight length price foreign
xsvmat, from(r(table)') rowname(parm) names(col) rowlab(label) list(,)

and create and list a dataset similar to those produced by the SSC 
package -parmest-, but with variable names conforming to a style that 
seems to be officially approved by StataCorp. These output datasets can 
alternatively be saved to a disk file and/or written to the memory, 
overwriting the original dataset, and can then be used to produce plots 
and/or tables.
I would like to thank Vince Wiggins of StataCorp for some helpful 
advice, at the 2013 UK Stata User Meeting, on the syntax to be used for 
this package.
Best wishes

Roger

TITLE
      xsvmat: Convert a matrix to variables in an output dataset

DESCRIPTION/AUTHOR(S)
      xsvmat is an extended version of svmat.  It creates an output
      dataset (or resultsset), with one observation per row of either
      an existing matrix or the result of a matrix expression, and
      data on the values of the column entries in that row, and,
      optionally, extra variables specified by the user.  The output
      dataset created by xsvmat may be listed to the Stata log, or
      saved to a disk file, or written to the memory (overwriting any
      pre-existing dataset).
