Of course, sorry I was being stupid A From: Benilton Carvalho [mailto:Benilton.Carvalho@cancer.org.uk] Sent: 31 October 2012 13:39 To: Benilton Carvalho; guest@bioconductor.org; bioconductor@r-project.org; a.beggs@bham.ac.uk Cc: Benilton Carvalho Subject: Re: Passing multiple files to pdInfobuilder Auto correct problem, sorry. You should pass only 1 of your xys files. All that the builder needs is 1 xys as a template. Sent from a mobile device. Please apologise for brevity, spelling and punctuation.

I am trying to feed them into pdInfobuilder using the script below, but it crashes out with the following error: Error in validObject(.Object) : invalid class “ScalarCharacter” object: ScalarCharacter must have length one Does this mean that pdInfobuilder can only take one file at a time?
