say, a 1 for e(TR) and 2 for e(TC)), resulting in an (R + C) x (j +1) matrix, and then export the matrix, with rownames, to an ASCII comma-separated file. Can this be done and how? * * For searches and help try: *http://www.stata.com/support/faqs/res/findit.html ...
local names : rownames M gen str rown = "`names'" and got the variable rown, but it's blank. I also used gen str rown = `names' but got an error message saying Frag300 not found. How do I save the row names as a variable? I'm using Stata 10 on a Vista machine. * * ...

我们在Stata中使用矩阵时,有时需要给它们一个自定义的名称,这时我们在命令matrix后面分别添加命令rownames和colnames就能完成对矩阵行和列的命名。在Stata中对于任意一个新读入的矩阵,系统会自动赋予行名和列名,分别为r1,r2,…;c1,c2,…。 首先读入矩阵A并且展示一下矩阵A,可以看到矩阵A的行名称和列名称分别为r1,...
