Subject   st: New versions of -sencode- and -sdecode- on SSC
Date   Wed, 29 Mar 2006 16:27:32 +0100

Thanks to Kit Baum, new versions of the -sencode- and -sdecode-
(described as below on my website) are now available for download from
SSC. In Stata, use the -ssc- command to do this.

-sencode- and -sdecode- are super versions of -encode- and -decode-,
respectively. The new versions both contain my new affiliation and email
in the on-line help files. The new -sdecode- also adds the new options
-prefix()- and -suffix()-, specifying strings to be added to the left or
right (respectively) of the decoded string variable.

TITLE
      sencode: Encode a string variable non-alphanumerically into a
numeric variable

DESCRIPTION/AUTHOR(S)
      sencode is an extended version of encode. It takes, as input, a
string
      variable, and generates, as output, a numeric variable, with value
labels
      corresponding to values of the string variable. The output numeric
variable
      may replace the input string variable or be generated as a new
variable.
      sencode orders the numeric values corresponding to string values
in the
      sequential order of appearance in the input string variable in the
data set,
      or in another order specified by the user, instead of ordering
them in
      alphanumeric order of the string value, as encode does. The
mapping from
      numeric code values to string labels may be one-to-one (coded in
order of
      first appearance of the string value) or many-to-one (coded in
each
      observation by the position of that observation in the data set,
or in the
      user-specified ordering).

package sdecode from http://www.imperial.ac.uk/nhli/r.newson/stata7

TITLE
      sdecode: Decode a numeric variable to string, formatting
unlabelled values

DESCRIPTION/AUTHOR(S)
      sdecode is an extended version of decode. It takes, as input, a
numeric
      variable, and generates, as output, a string variable, with values
      corresponding to value labels of the numeric variable for labelled
values,
      and (optionally) formatted values of the numeric variable for
unlabelled
      values. The output string values therefore appear as the numeric
input
      values appear in output from the tabulate command. The output
string
      variable may replace the input numeric variable or be generated as
a new
      variable.
