[Gretl-devel] extracting row names of a matrix

Dear all, #<hansl function string get_rnames(matrix M)    string s = sprintf("%d",M)    nss = nlines(s)    string line    scalar i = 1    strings S = array(nss)    loop while getline(s, line) -q        S[i]= sprintf("%s",  line)        i++    endloop    ret = ""    if nelem(strsplit(S[1])) == 2        loop i = 1..nss -q            ret = ret~" "~strsplit(S[i])[1]        endloop        ret = strstrip(ret)    endif    return ret end function # example M = I(2) M[1,1] = NA rownames(M, "a b") eval get_rnames(M) #hansl> output: ? eval get_rnames(M) a b Is there a less roundabout way to extract row names of a matrix Oleh
