It climbs to $16k+ for the 'Premium' commercial version of SPSS. Ouch. A commercial license SAS is similarly expensive, once you're beyond the basics. And a 'student' academic SAS license does expire. The equivalents to all that are, of course, entirely free in R.

Within Stata I searched for "search package, all" which returned 499 results and "search command, all" which returned 697 results. I copied the first line of each of the list which lists just the name or url and removed duplicates. My list has 1325 items, I have included it here with commas separating each value. It is worth noting that packages in Stata are not the same as packages in R. All packages that I am aware of in Stata only have a single command. In R, it is almost always the case that multiple functions/commands are bundled within the same package.<br /><br />Looking at the base folder in Stata, I searched for *.ado and found a little over 23 hundred ado files which are individual commands. However, some if not many of these ado files are shortcuts for other commands. Thus many commands are counted too many times such as reg regr rege reges regress all are the same command.<br /><br />I also wanted to say that I don't think it was entirely foolish for Stata to not embrace the blogging community and in particular my blog. I started blogging in Stata and initially I received several encouraging emails from the corporation I eventually ended up writing some posts which were unflattering to the organization. Some of which they responded to.<br /><br />However, by the time it came to me starting the aggregator, I think they already had decided as a cooperation to distance themselves from the blogging community since I was not the only blog out there which had written posts in favor or R over Stata.<br /><br />List of Stata commands<br />https://gist.github.com/EconometricsBySimulation/9958775Francishttps://www.blogger.com/profile/16658586705916884436noreply@blogger.comtag:blogger.com,1999:blog-6288862798546085706.post-2904197926630478982014-04-03T12:44:02.650-04:002014-04-03T12:44:02.650-04:00Hi Bob, I wanted to mention that I looked more clo...Hi Bob, I wanted to mention that I looked more closely at the google trends data and am not convinced I believe the graph any more. The primary problem is that the top search result by far is \r which is a character likely referenced in many languages.<br /><br />As for the number of commands in Stata. I am pretty sure that number is very low as well compared with R. It is just so much harder to write commands in Stata syntax. I have had extensive experience with it yet still find it difficult and counter intuitive. It is all because of the temperamental way Stata parses commands using spacing and ordering.Francishttps://www.blogger.com/profile/16658586705916884436noreply@blogger.comtag:blogger.com,1999:blog-6288862798546085706.post-83238604850858706482014-04-03T08:37:35.618-04:002014-04-03T08:37:35.618-04:00Thanks for pointing out the new Google Trends feat...Thanks for pointing out the new Google Trends feature. It took me a while to figure out that if you enter "Stata" it automatically suggests "Stata software" but when you enter "R" it does not offer variations. However, if you type "R programming" it will then offer "R Programming Language". Very nice! I'll probably add this back to my popularity article that you reference.<br /><br />It's crazy that Statacorp did not want to syndicate its blog to stata-bloggers.com! Companies should be doing all they can to encourage their users to offer them free marketing. <br /><br />Do you know how to count the number of commands in Stata? I did so for SAS and found that R was adding more new commands in one year than SAS added in 40 (http://r4stats.com/2013/03/19/r-2012-growth-exceeds-sas-all-time-total/). I suspect the same is true for Stata. The commands are directly comparable of course, but it is a measure that puts R phenomenal growth in perspective.<br /><br />Cheers,<br />Bob MuenchenBob Muenchenhttps://www.blogger.com/profile/14224906531398701275noreply@blogger.comtag:blogger.com,1999:blog-6288862798546085706.post-12045731347298683362014-03-29T18:16:33.674-04:002014-03-29T18:16:33.674-04:00Thank you, sorry about that.
