The load option with output argument then your variables become fields of that struct which allows you to rename them renaming variables themselves is not a fun task.
Change row name mat stata.
I have never before however seen a stata matrix whose row or column names begin with digits.
My final goal is a tab delimited text file that will be imported into a word processor to create a table like the one below.
No names informs stata whether variable names are included on the first line of the file roberto ferrer feb 7 16 at 23 54.
The tricks and shortcuts mentioned were introduced with stata 12 0.
But let me refer here to the stata help at help rename group.
Which names matrix tokenize names local where newname local newnames matrix which names matrix newnames end examples.
Row names returns a data frame with the row names changed.
Older versions of stata.
Row names is similar to rownames for arrays and it has a method that calls rownames for an array argument.
See here note that stata won t let you name a variable 1960 1961 etc they can t begin with a number so i would go into the csv file or excel and manually rename them y1960 y1961 etc.
Matrcrename z col 3 some alternative.
Mat li z symmetric z 3 3 x y z a 1 b 1 1 stata 1 1 1.
A quick review in the user manuals has not turned up anything to say that it is illegal but it is also clear from the text and all examples that stata matrix row and column names are often intended to match variable names and of course a variable name cannot.
If you load the mat file into a struct i e.
Rename does not include the syntax variable unless that is a variable name.
You can then save the struct back out to the mat file with the struct flag.
Matrcrename z col 4 sas column out of range r 498.
Transform the values to valid variable names strip out blanks invalid characters shorten load them into a macro variable.
Matrcrename z row 3 stata.
In that case i will continue to use the solution suggested by stata tech support which changes value labels before any matrices are created.
Mat li z symmetric z 3 3 x y z a 1 b 1 1 c 1 1 1.
Read the first row.
In contrast the question mark stands for a single character in a variable name.
Prior to that some other commands such as the following were available.
This will work at least this far.
Start reading at row 2 use the macro variable from step 1 after an input statement.
Using stata mat c 2 1 5 1 3 4 5 4 2 mat lis c symmetric c 3 3 c1 c2 c3 r1 2 r2 1 3 r3 5 4 2 mat ct c mat lis ct symmetric ct 3 3 r1 r2 r3 c1.
