I will offer a short tutorial on R/qtl at the QTL-MAS Workshop in Poznań, Poland
Because of the large forum and the short amount of time for the tutorial, I think it'd be best to just do this as a "demonstration". I'll have to move through things quickly; I'll cover highlights from the PDF file below.
Nevertheless, if you are interested in following along on your own laptop, you should download and install R and R/qtl, and the additional files (below), in advance. You may also wish to print out the PDF of the tutorial.
Download and run the installer for R version 2.11.0: R-2.11.0-win32.exe
Download and run the installer for R version 2.11.0: R-2.11.0.pkg
Install R as above, then start R and from the R command prompt type install.packages("qtl")
You will need internet access.
Download the following additional files, and place them somewhere that you can get to them:
| rqtltour2.pdf | The text of the tutorial (you might want to print this out) | |
| rqtltour2.R | The R code for the tutorial | |
| sug.csv | The data we'll consider (from Sugiyama et al., Physiol Genomics 10:5-12, 2002) | |
| various.RData | Results of some intermediate calculations, which will save us time |
