August 25, 2011
By

I doubt if anyone would deny the importance of being able to reproduce one's econometric results. More importantly, other researchers should be able to reproduce our results to verify (a) that we've done what we said we did; (b) to investigate the sensitivity of our results to the various choices we made (e.g., functional form of our model, choice...

Using Emacs to work with R

A simple yet efficient way to work with R consists in writing R code with your favorite text editor and sending it to the R console.

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?).
