Axis break in R for line plot
Planning to draw a density line-plot with gapped (or broken) Y-axis in R, I initially tried out the plotrix package. However after facing a couple of problems, I ended up using the standard R graphics codes to draw the correct gapped line-plot.Here I will only apply the break to the y-axis of a density line-plot, however similar metho...

Venus (female) and Mars (male) symbols in R plot – using Unicode
When analyzing a data constructed of individuals (or samples from individuals) of both male and female of a species (e.g. humans), often it is a good idea to compare the distribution of the various studied parameters for the males to those for the females. As for instance in RNAseq analysis, it is the measured expression of many genes may differ ...

New Book: "Computational Genomics with R"
It costs now 299$ now to sequence your genome [https://nebula.org/whole-genome-sequencing-dna-test/]. It is getting cheaper to generate genomic data and more of it is coming through. We can’t see the same trend for the people who can analyze the data. There is always a shortage of people who can do decent analysis of genomic data. We need to ...

Speeding up aldex.effect()
I’ve been optimizing various functions in ALDEx2 on Bioconductor to make it more efficient. One bottleneck has been the aldex.effect() function which calculates an effect size for the difference between distributions. I will write a separate post on how this calculation works, but I’m happy to say that the new effect size calculation is ab...
