Merging Two Different Datasets Containing a Common Column With R and R-Studio

Another way for the database challenged (such as myself!) for merging two datasets that share at least one common column… This recipe using the cross-platform stats analysis package, R.

RStudio 0.94.92 visited

I just updated my RStudio version to the latest, v.0.94.92 (will this asymptotically approach 1, or actually get to 1?). It was nice to see the number of improvements the development team has implemented, based I’m sure on community feedback. The team has, in my experience, been extraordinarily responsive to user feedback, and I’m sure

Just as scientists should never really have to think much about statistics, I feel that, in an ideal world, statisticians would never have to worry about computing. In the real world, though, we have to spend a lot of time building our own tools.It would be great if we could routinely run R with speed and memory limitations...

In an earlier post I went through some econometrics that involved the problem of testing for multivariate cointegration in the case where there are one or more trend-breaks or level-breaks in the time-series data.  Specifically, I talked about the modified Trace tests introduced by Johansen et al.

In comments on a recent post, "Ben" and Tal Galili very sensibly asked if I could make R code available for the econometric analysis in my posts, in addition to EViews code. I'll be trying to do this wherever I can, given the time constraints.

The important point implicit in these comments is that R is free, open-source, software, whereas...
