(The examples here work with the version of insidefunctor tagged as "v1")
I ran into an interesting problem using "inside" functors.
Something is wrong in the following code (well, depending on what you thought it should do).
> library(insidefunctor)
> `%+.%` = fmap(`+`)
> x = seq(0, 10, len = 50)
> plot(x,...
The solar irradiance incident outside the earth’s atmosphere is called the extraterrestial or extra-atmospheric irradiance. It is derived from the solar constant only with geometric equations. It can be easily calculated with the calcSol function of the solaR package. With this post I will show an example with some packages from the Spatial task view. 
This is an example piece of code for the Overfitting competition at kaggle.com. This method has an AUC score of ~.91, which is currently good enough for about 38th place on the leaderboard. If you read the completion forums closely, you will find code...
At the department we have been analyzing some transaction data for some time. We got a new dataset with lots of transactions. Once you need interpurchase (IPT) times, posix is quite useful, as you can easily difference transactions to generate IPTs.So ...
The latest release of Revolution R Enterprise shows how Revolution Analytics’ package for big data, RevoScaleR, is continuing add new capabilities for Big Data statistics. RevoScaleR removes the limits on the size of the data that can be processed in R through the use of the highly efficient .Xdf binary file format. Xdf stores data by rows within columns...
Suppose you're working on a problem that involves a loop for calculations. At each iteration inside the loop, you want to construct a plot. Not only do you want to see the plot, but you would like to save each plot for a presentation, report or paper...

Here is some code to run Phylip's contrast application from R and get the output within R to easily manipulate yourself. Importantly, the code is written specifically for trait pairs only as the regular expression work in the code specifically grabs da...
