Analyzing Microbial Growth with R

In experimental evolution research, few things are more important than growth. Both the rate of growth and the resulting yield can provide direct insights into a strain or species’ fitness. Whether one strain with a trait of interest can outgrow (and outcompete) another that possesses a variation of that trait often depends primarily on the fitnesses of the two...

Using R to model the classic 60/40 investing rule

Image by Timothy Poulton   A long-standing paradigm among savers and investors is to favor a mixture of 40% bonds and 60% equities. The simple rationale is that stocks will provide greater returns while bonds will serve as a diversifier when if equities fall. If you are saving for your pension, you probably heard this

Get notified when R packages update

Today’s highly active R user base is developing, re-developing, and releasing R packages at a never-before-seen rate. While this is fantastic news for the R community as such, it inevitably also causes growing pains as mentioned before. One of the often cited problems is the painful and time-consuming task to keep track of changes and version updates of

Earthquake Magnitude / Depth Chart

I am working on a project related to secondary effects of earthquakes. To guide me in the analysis I need a chart showing the location, magnitude and depth of recent earthquakes. There are a host of such charts available already, but since I had the required data on hand, it seemed like a good idea

Author inflation in academic literature

There seems to be a general consensus that author lists in academic articles are growing. Wikipedia says so, and I’ve also come across a published letter and short Nature article which accept this is the case and discuss ways of … Continue reading →

Flip the script, or, the joys of coord_flip()

Has this ever happened to you?I hate it when the labels on the x-axis overlap, but this can be hard to avoid. I can stretch the figure out, but then the data become farther apart and the space where I want to put the figure (either in a talk or a paper...

The Collatz Fractal

It seems to me that the poet has only to perceive that which others do not perceive, to look deeper than others look. And the mathematician must do the same thing (Sofia Kovalevskaya) How beautiful is this fractal! In previous posts I colored plots using module of complex numbers generated after some iterations.

Adding Annotation to R Objects

When you take a photograph, you can include the date in the image, so you remember when you created it.  (In fact, under EXIF format, it’s stored in the image file anyway, even if it doesn’t appear in the picture.)  Wouldn’t it be nice to make annotations in the objects you create under R? For
