Writing from the previously mentioned intro to R course at the Kennedy Center. If you couldn't make it you can download all the course materials from Theresa Scott's website, under the "Current Teaching Material" heading. Here is a direct link to the PDF for the overview materials that we're going over today, along with the R code from the examples in this guide.
The New York Times published this interesting article on how the ability to design and perform computer simulations is a highly marketable skill for careers across many disciplines.In methodology development we use simulation nearly every day.
I've linked to UCLA's stat computing resources once before on a previous post about choosing the right analysis for the questions your asking and the data types you have.
The Vanderbilt Kennedy Center is offering a free (repeat, free) one-day introductory course to the R statistical computing language on June 23, taught by Theresa Scott from the department of Biostatistics. You can find contact/registration info at the link below.Vanderbilt Kennedy Center - An Introduction to the Fundamentals &
OpenHelix offers free access to a handful of their tutorials on genomics and bioinformatics resources, including the UCSC Genome Browser, Seattle SNPs, Genome Variation Server, and the VISTA Comparative Genomics tools.
A reader asked yesterday how you would merge data from two different files. For example, let's say you have a ped file with genotypes for individuals, and another file that had some other data for some of the individuals in the pedfile, like clinical or environmental covariates.
And it will do way more than display "Hello, world!" to the screen. An anonymous commenter on one of our Linux posts recently asked how to write scripts that will automate the same analysis on multiple files. While there are potentially several ways to do this, perl will almost always get the job done.
`screen` is one of the most useful system tools I've ever used. It allows you to begin a process and then detach from the process to let it continue to run in the background.
Last week I posted a one-page reference guide that gives a short description of the Linux commands I most commonly use. To accompany this, here is a detailed walkthrough filled with examples that will introduce any beginner to the basics of using Linux in just a few hours.
Whenever we have new students rotating through our lab who've never used Linux I always end up scrounging around the world wide series-of-tubes only to find some command line reference that's not really useful for students. So I made my own one-page reference guide that gives a basic description of most of the commands most of you will use. Feel free to distribute.
