The R language completely integrates accessing and handling facts, operating analytic procedures, executing repetitive “macros", handling output (as SAS ODS or SPSS OMS) and including new functions by way of matrix algebra capabilities all in one consistent kind of programming. Other computer software generally makes use of a special language for every of These steps (4).
Be aware that the initial event of age Here's the identify on the macro and the second will be the title of the variable. I utilized quotations for making the code clearer. Stata hardly ever will get bewildered.
.65153125 Another way to drive evaluation would be to enclose e(r2) in one offers after you determine the macro. This is called a macro expression
It is always a smart idea to commence just about every do file with opinions that come with at least a title, the identify of the programmer who wrote the file, and also the day. Assumptions about required data files must also be noted.
