In the previous post we saw how much convenient could be GenABEL in the management of genotypic/phenotypic data.
We introduced the import of genotypic data from an Illumina format file:
> convert.snp.illumina(inf = "gen.illu", out = "gen.raw", strand = "file")
but what happens if you're analysing your data with PLINK, the open source toolset for GWAS?
This article gives a brief overview of the data.table package written by M. Dowle, T. Short, S. Lianoglou.
A data.table is an extension of a data.frame created to reduce the working time of the user in two ways:
- programming time
- compute time
Here is a little overview on GenABEL library developed by Yurii Aulchenko (www.genabel.org/).
GenABEL is a full-featured R library for dealing with Genome-Wide Association analysis of binary and quantitative traits.
Andrea Spanò, founder and partner at Quantide, held two seminars about Industrial Statistics at the University of Bergamo.
Process Capability Analysis and Gage R&R were topics of seminars.
