No names informs stata whether variable names are included on the first line of the file roberto ferrer feb 7 16 at 23 54.

Change row name mat stata.

I have never before however seen a stata matrix whose row or column names begin with digits. Both import excel and import delimited will let you specify that the first row contains variable names. Prior to that some other commands such as the following were available. Computing column row means mat cm c rowsof a mat lis cm cm 1 2 c1 c2 r1 1 1 6666667 horizontal concatenation.

But let me refer here to the stata help at help rename group. Rename does not include the syntax variable unless that is a variable name. 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. Transform the values to valid variable names strip out blanks invalid characters shorten load them into a macro variable.

Older versions of 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 stata 1 1 1. The tricks and shortcuts mentioned were introduced with stata 12 0.

Matrcrename z row 3 stata. Matrcrename z col 3 some alternative. This will work at least this far. Which names matrix tokenize names local where newname local newnames matrix which names matrix newnames end examples.

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. Mat li z symmetric z 3 3 x y z a 1 b 1 1 c 1 1 1. 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. If you load the mat file into a struct i e.

Matrcrename z col 4 sas column out of range r 498. Row names returns a data frame with the row names changed. Read the first row. You can then save the struct back out to the mat file with the struct flag.

Row names is similar to rownames for arrays and it has a method that calls rownames for an array argument. Start reading at row 2 use the macro variable from step 1 after an input statement. 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.
