Theory and Practice

Slow Merging in R (using row.names). I spent a lot of time this summer messing around with R and manipulating data in a variety of forms (matrices, data frames etc.). R has an easy builtin function for merging matrices (or data frames). For example, it’s simple to merge by row (i.e. to aggregate samples of the expression level of the same gene). If using a matrix, then the gene names are stored in row.names (i.e. Merge(mat1, mat2, by = "row.names". Merge(df1, df2, by = "GeneName". Merges the two matrices...

RStudio: The Good and the Bad – Theory and Practice

https://nrjones8.wordpress.com/2013/07/20/rstudio-the-good-and-the-bad

RStudio: The Good and the Bad. With that said, there are definitely some improvements that could be made. Perhaps I’m spoiled as a Sublime Text user for Python/Ruby development, but I’d love to see some of Sublime’s functionality incorporated into RStudio. Here are a few things that frustrate me about RStudio, and please let me know if you have suggestions about fixing these gripes! Key bindings. Why are these not customizable! Why restrict what can be shown in each pane? July 20, 2013. Blog at WordPress...

With the rise in available resources, MOOCs, and the need for more people with technical backgrounds in industry, this is a popular question today. Studying CS at a liberal arts school, it’s been stressed over and over that “computer science” is really the study of algorithms; that is, given a problem, how can we go about solving it? Nothing. For Calc I? Better yet, Tynker is completely browser-based and therefore doesn’t require a ton ...
