QROWNAME: Stata module to extract lists of quoted row and column names from a matrix

qrowname returns lists of double-quoted row equations, row names and row full names for a matrix specified by matrix_name. qcolname returns lists of double-quoted column equations, column names and column full names for a matrix specified by matrix_name. The lists are stored in the saved results r(eq), r(name) and r(fullname), containing lists of quoted row/column equation names, quoted row/column names and quoted row/column full names, respectively. The two commands work similarly to the macro extended functions roweq, coleq, rownames, colnames, rowfullnames and colfullnames, but, unlike the macro extended functions, they return each name in double quotes. This is useful when row and column equations contain spaces or even single quotes, as sometimes happens with equation names for matrix estimation results generated by mlogit when the multinomial outcome variable has value labels. The returned lists can then be assigned to other matrices using the matrix roweq, matrix coleq, matrix rownames and matrix colnames commands.
