After I spoke tonight at the NYC R meetup, John Myles White and Drew Conway told me about this competition they’re administering for developing a recommendation system for R packages. They seem to have already done some work laying out the network of R packages–which packages refer to which others, and so forth.
I just hope they set up their system so that my own packages (“R2WinBUGS”, “r2jags”, “arm”, and “mi”) get recommended automatically. I really hate to think that there are people out there running regressions in R and not using display() and coefplot() to look at the output.
P.S. Ajay Shah asks what I mean by that last sentence. My quick answer is that it’s good to be able to visualize the coefficients and the uncertainty about them. The default options of print(), summary(), and plot() in R don’t do that:
– print() doesn’t give enough information
– summary() gives everything to a zillion decimal places and gives useless things like p-values
– plot() gives a bunch of residual and diagnostic plots but no graphs of the fitted model and data.
I like display() because it gives the useful information that’s in summary() but without the crap. I like coefplot() too, but it still needs a bit of work to be generally useful. And I’d also like to have a new function that automatically plots the data and fitted lines.
