Thank you for your answer. I have tried this but it didn't work. I think the reason for this is that the text was originally entered in the matrix not as strings e.g. not
X = { "Marl" "Winf"}
but
X = {Marl Winf}

If the data is 'character' data i.e. characters packed inside matrix elements, then you need to use the function uniqIndx. The last input to uniqIndx is a flag to tell the function whether your input is numeric or character data. Here is an example:
//Create matrix of character data vnames = { gdp M2, t-bill gdp, exports gdp }; //Transform data to a vector vnames = vecr(vnames); //Find index of unique elements is_numeric = 0; u_idx = uniqIndx(vnames, is_numeric); print "unique variable names include: " $vnames[u_idx];
