In Word, keeping track of figure numbers is a big pain, even more so when figures are moved between the main manuscript and the supplement. Moving my Word manuscript to ... [Read more...]

Coming from Python, the absence of a real dictionary in R has annoyed me for quite some time. Now, I actually needed to use vectors as keys in R:__ library(dict)__ d -____ d[[1]] __ d[[c(2, 3)]] __ d[["foo"]] __ d[[1]][1] 42__ d[[c(2, 3)]][1] "Hello!"Under the hood, separate C++ dictionaries (unordered_map) ...

As a rule, everything I discover in R has already been discussed by Hadley Wickham. In this case, he writes:The reason why the C++ function is faster is subtle, and relates to memory management. The R version needs to create an intermediate vector the ... [Read more...]

So far, I have been preparing composite figures by plotting the data using ggplot2, and then putting the panels together in OmniGraffle or Adobe Illustrator. Of course, every time the data is updated, I would need to go back to the vector editing progr... [Read more...]

I have two 2D distributions and want to show on a 2D plot how they are related, but I also want to show the histograms (actually, density plots in this case) for each dimension. Thanks to ggplot2 and a Learning R post, I have sort of managed to do what ... [Read more...]
