One of my more popular posts is A brief introduction to “apply” in R. Come August, it will be four years old. Technology moves on, old blog posts do not.
So: thanks to BioStar user zx8754 for pointing me to this Stack Overflow post, in which someone complains that the code in the post does not work as described. The by example is now fixed.
Side note: I often find “contact the author” is the most direct approach to solving this kind of problem ;) always happy to be contacted.
Which topics are the most popular at the BioStar bioinformatics Q&A site?
One source of data is the tags used for questions. Tags are somewhat arbitrary of course, but fortunately BioStar has quite an active community, so “bad” tags are usually edited to improve them. Hint: if your question is “How to find SNPs”, then tagging it with “how, to, find, snps” won’t win you any admirers.
OK: we’re going to grab the tags then use a bunch of R packages (XML, wordcloud and ggplot2) to take a quick look.
