Top 100 R packages for 2013 (Jan-May)!
(This article was first published on R-statistics blog » RR-statistics blog, and kindly contributed to R-bloggers) What are the top 100 (most downloaded) R packages in 2013? Thanks to the recent release of RStudio of their “0-cloud” CRAN log files (but without including downloads from the primary CRAN mirror or any of the 88 other CRAN mirrors), we can now answer this question...
Mini-tutorial for Quandl: How to access financial data with R
by Joseph Rickert Quandl.com, the open source website for financial data, made rapid progress earlier this year in becoming an R friendly source for financial time series data. Tammer Kamel, Quandl’s founder introduced the site on Revolutions blog in late February as a “search engine” for numerical data and explained how Quandl’s “Q-bot” can take data from almost any...
The null model for age effects with overdispersed infection
How does overdispersion of infections affect the behavior of the multiple-infection model? I redefine the model to account for overdispersion, assuming the same overdispersion occurs in both age classes. The parameter varies inversely with the degree of overdispersion. Again, the classes are demographically identical, and infection affects mortality but not growth:
\[\begin{aligned} \frac{dJ}{dt}...
Plotting average read and write operation size by ASM disk for Oracle
Throughput, throughput, throughput – for many databases, this is the performance measure of importance. When you are working with a fixed number of IOPS but see mixed workload types, system health can be assessed through the average read and…
A Null Model for Age Effects in Disease with Multiple Infections
(This article was first published on Noam Ross - R, and kindly contributed to R-bloggers) Here’s a little thought exercise I did that has caused me to go back and restart my Sudden Oak Death modeling in a new framework. Feedback welcome. I’m especially interested in relevant literature – I haven’t found many good examples of macroparasite/multiple infection models...
Finally! Tracking CRAN packages downloads
The guys from RStudio now provide CRAN download logs (see also this blog post). Great work! I always asked myself, how many people actually download my packages. Now I finally can

Intro to Parallel Random Number Generation with RevoScaleR
by Joseph Rickert Random number generation is fundamental to doing computational statistics. As you might expect, R is very rich in random number resources. The R base code provides several high quality random number generators including: Wichmann-Hill, Marsaglia-Multicarry, Super-Duper, Mersenne-Twister, Knuth-TAOCP-2002 and L’Ecuyer-CMRG. (See Random for details.) And, there are at least three packages, rspring, rlecuyer, and rstream for...
Fixing My Internet With R and Python
Last summer, I had some internet connectivity problems. Specifically, I would have massive latency issues that affected my conversations on Skype and my relatively pathetic under the best of circumstances efforts at online gaming. It was driving me up a wall and I couldn't figure it out. It hadn't...
