R Robustreg Package Downloads

I built robustreg in 2006 and at the time the major stat packages did not have a robust regression available.  Below are graphs of weekly and cumulative downloads from just the RStudio mirror.  I would estimate total downloads at over 150,000.

The median_rcpp() function is written in C++ and is multiple times faster than the R base function median().

> r_norm<- rnorm(1000000)

 > system.time(median(r_norm))
   user  system elapsed 
  0.040   0.004   0.044 
> system.time(median_rcpp(r_norm))
   user  system elapsed 
  0.011   0.000   0.011 

 > median(r_norm)
[1] -0.001214243
> median_rcpp(r_norm)
[1] -0.001214243
