The rbokeh package version 0.4.1 was recently released. The most major addition in 0.4 is support for javascript callbacks for custom interactivity, which I’ll provide an example of below and will be posting about in more detail soon. Thanks to i...
Keeping track of versions You work on a project and would like to keep track of what you did. That is why keep old versions of your files. That way you can go back if you messed up beyond recognition. Usually that looks like this: Or you use dropbox or something like it: Other people use email. Emailing to themselves or to collaborators...
TL DRs Time ago I changed my humble moto G 1st gen with a more big Mate Ascend 7 and my thumb did things I didn’t know to reach the opposite top corner. In one of this efforts to reach a far icon I remembered the phone evolution image. And then I asked how true is this image. How similiar is...
One of benefit of integrating R with PowerBI is access to rich array of data visulizations not present in the standard PowerBI loadout. R is practically unlimited in the types of graphics it can create (although the amount of programming required can vary from a few lines using an existing R package, to large custom functions for truly bespoke...
Conway’s Game of life is probably the most famous cellular automaton, consisting of a grid of cells developing according simple rules. Today, we’re going to add mutation and selection to the game, and see let patterns evolve. The fate of a cell depends on the number cells that live in the of neighbouring positions. A
Given a data frame with multiple columns which contain time series data, let’s say that we are interested in executing an automatic forecasting algorithm on a number of columns. Furthermore, we want to train the model on a particular number of observations and assess how well they forecast future values. Based upon those testing procedures,
To answer the issue, I extend the covplot function to support viewing coverage of a list of GRanges objects or bed files. library(ChIPseeker) files
2 Years, are a long time. For a blogger wannabe for sure. 2 years since my last post, a lot has happened and my skills have broadened beyond R, so this R dedicated blog, might not speak about R so much, maybe some other things. I’ve received some good comments from readers and friends on my contribution
This is based on joint work with Gregor Aisch and Josh Keller of the New York Times. A new package gunsales is now on the CRAN network for R. It is based the NYTimes/gunsales repository underlying the excellent New York Times visualizations, first published first in December 2015 and updated with more recent data since. The analysis takes public government data...
Refining the credit model(s) To continue with the creditworthiness case, I want to explore this case a little bit more by adding more meta algorithms such as boosting, winnowing, cross validation etc. Additionally, I’ll use randomforest as classifier algorithm. I’m still using the same german credit data as in the previous post. I’m also using the same train/testest. Each model is...
