DAVID functional analysis with clusterProfiler

clusterProfiler was used to visualize DAVID results in a paper published in BMC Genomics. Some users told me that they may want to use DAVID at some circumstances. I think it maybe a good idea to make clusterProfiler supports DAVID, so that DAVID users can use visualization functions provided by clusterProfiler. Read More: 1642 Words...

How to Make a Histogram with ggvis in R

The two previous posts described how you can make histograms with basic R and the ggplot2 package. This third and last part of our histograms tutorial will look at how to make a histogram with ggvis.

Sparse Quadratic Programming with Ipoptr

This post is a follow up to my last post on quadratic programming facilities in R. A commenter pointed me to the ipoptr project which exposes an R interface to the COIN-OR optimization routine Ipopt. COIN-OR is a suite of optimization utilities implemented in C++ and supported by a back-end of configurable FORTRAN linear...
