Make your R simulation models 20 times faster – (This article was first published on Bluecology blog, and kindly contributed to R-bloggers) Make your R simulation models 20 times faster R can be frustratingly slow if you use its loops. However, you can speed it up significantly (e.g. 20 times!) using the Rcpp package. That could turn a day long simulation into an hour long simulation. I had heard years ago about the Rcpp package. Rcpp lets you write and use C ++ functio… http://ow.ly/ThnD509QL3U

ggraph: ggplot for graphs – A graph, a collection of nodes connected by edges, is just data. Whether it’s a social network (where nodes are people, and edges are friend relationships), or a decision tree (where nodes are branch criteria or values, and edges decisions), the nature of the graph is easily represented in a data object. It might be represented as a matrix (where rows and columns are nodes, and elements mark whether an edge between them is present) or as a da… http://ow.ly/ahmF509QL3W

RSurvey – (This article was first published on jfisher-usgs, and kindly contributed to R-bloggers) Early in my science career I believed that any good piece of software included a graphical user interface (GUI). That was many years ago, and during that time I delved deep into the art of Tcl/Tk programming; using the tcltk package to create GUI’s in R. Countless hours were spent struggling over the R-Tcl/Tk interface and educating myself on the best practices and princip… http://ow.ly/Q26S509QL3Y
