Row names of the form 1 n for n 2 are stored internally in a compact form which might be seen from c code or by deparsing but never via row names or attr x row names.
Change row name mat stata.
Row names returns a data frame with the row names changed.
Transform the values to valid variable names strip out blanks invalid characters shorten load them into a macro variable.
Prior to that some other commands such as the following were available.
Start reading at row 2 use the macro variable from step 1 after an input statement.
No names informs stata whether variable names are included on the first line of the file roberto ferrer feb 7 16 at 23 54.
Matrcrename z row 3 stata.
If you load the mat file into a struct i e.
In contrast the question mark stands for a single character in a variable name.
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.
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.
Row names is similar to rownames for arrays and it has a method that calls rownames for an array argument.
Rename does not include the syntax variable unless that is a variable name.
Which names matrix tokenize names local where newname local newnames matrix which names matrix newnames end examples.
Computing column row means mat cm c rowsof a mat lis cm cm 1 2 c1 c2 r1 1 1 6666667 horizontal concatenation.
Mat li z symmetric z 3 3 x y z a 1 b 1 1 c 1 1 1.
The tricks and shortcuts mentioned were introduced with stata 12 0.
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.
You can then save the struct back out to the mat file with the struct flag.
But let me refer here to the stata help at help rename group.
Older versions of stata.
Matrcrename z col 4 sas column out of range r 498.
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.
I have never before however seen a stata matrix whose row or column names begin with digits.
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.
In that case i will continue to use the solution suggested by stata tech support which changes value labels before any matrices are created.
Read the first row.
