Hi, is there any way for an autimatic loading of the corresponding annotation packages. I have to analyze 15 different datasets with different AffyBatches from different chip types. I want to do something like that: library(affy) library(ALL) data("ALL") l <- paste(annotation(ALL), "db", sep=".") library(l) Fehler in library(l) : es gibt kein Paket 'l' Any ideas?

Hi Markus, you will need to use library(l, character.only = TRUE). HTH. J. Markus Schmidberger wrote: > Hi, > > is there any way for an autimatic loading of the corresponding > annotation packages.

Hi, Markus, Try this: library(l, character.only=TRUE) Chao-Jen Markus Schmidberger wrote: > Hi, > > is there any way for an autimatic loading of the corresponding > annotation packages.
