I am working in R.1.6.1 under win98 and was trying the getBioC() installation. I get the following error messages and am not able to complete the installation. Afew days ago there was no problem with the installation on my office computer, so I am puzzled. Thanks for the efforts to make these packages for Affy chip users and spotted array. They are definitely allowing us some freedom to investigate our findings more thoroughly. Best, Mark Vawter > getBioC() Running getBioC version 1.2.1 ....
