Hi all,

I was wondering if it is possible to modified the header data in the fixed slots of a VCFHeader object ?

I got this error.

attr(fixed(header(vcf)),"header")$FILTER <- newDataFrame

Error in (function (classes, fdef, mtable)  : unable to find an inherited method for function ‘fixed<-’ for signature ‘"VCFHeader", "fixed"’

thank you.

Not sure where you got the call to attr<-(), just this should work:

fixed(header(vcf))$FILTER <- newDataFrame
