^egen^ [newvartype] newvarname ^= rmedf(^varlist^)^ [^if^ exp] [^in^ range > ]

Description -----------

^egen rmedf^ (via _grmedf.ado file) generates median (across the row, i.e. within the current observation) of varlist, missing values ignored. It essentially reshapes the data (and thus might require a lot of memory), unlike Nick J. Cox's @_grmed@ that constructs the median within the existing data file and requires much less memory. The latter however produces the resulting variable observation by observation and is thus rather slow.
