Re: st: Stata and R
.
Maybe my statement simply reflects greater familiarity with Stata than
R. But I have given R a fair amount of time, and feel I picked up
Stata more quickly and retained it better. When I first bought Stata,
I gave couple months of study to the user guide, to select entries
(regress, anova, logit, xtgee), and a programming course. I have give
about the same time now to R, and I have successfully used it with the
shapes package, some genetics packages, and with the commands nls()
and nlme() for pharmacological data.
I think the Stata documentation is better. People in the clinic have
said they find it hard to find the right documentation in R as they
need it, and it tends to be technical rather than explanatory. I
agree. However, a great number of R books have now been published,
filling in all levels of expertise. However, you will spend just as
much on those texts as on Stata documentation.
I have a better time of it with Stata graphics. I think graphics in
Stata are now just as good as R, maybe better with version 10. At the
last R meeting there were difficulties with graphics device aspect
ratio and Sweave that were not resolved after 20 minutes of fiddling
by the expert. Go figure. One the other hand, Sweave is a good reason
to use R. Having one file that contains your R code, and your results
write up, that produces a final PDF report, is smart reproducible
research:

My impression also may be tainted by what our R clinic is all about:
helping people at their wits end. I don't attend an R conquests clinic.

Just about every other week I drop into our R clinic for a coffee
break to listen to people's questions and maybe ask one myself. The
clinic is about general use questions, not especially about
Bioconductor packages, which is one reason to use R. The clinic is
run
by a very capable R expert. Originally I started going to the clinic
thinking to myself that well, maybe this would be the last version of
Stata I would buy, because R has come miles in development and
documentation. More often than not, however, I conclude the opposite,
and continue to regularly use Stata, thinking there is value is good
commercial products.
I am curious about why you come to such an conclusion?

One interesting function in R that I can't find in Stata is Frank
Harrell's nomogram function in the Design package, which essentially
is a graphical alternative to outreg or estout.
