How do I make an alien technology feel alien? If you are allocating lots of different sized objects with no game plan, your RAM will begin to look like swiss cheese - lots of holes throughout and no order to argument "intgroup" is missing in arrayQualityMetrics   > source("http://bioconductor.org/biocLite.R") > biocLite("ArrayExpress") > library...
