Hi I've got two objects of class AnnotatedDataFrame and would like to combine them in the style of 'cbind'. How is this done? Is there really no method defined for 'cbind' and 'AnnotatedDataFrame' or am I overlooking something? What I mean is that this here works with ordinary data.frames: > df1 <- data.frame( A=1:5 ) > df2 <- data.frame( B=11:15 ) > cbind( df1, df2 ) A B 1 1 11 2 2 12 3 3 13 4 4 14 5 5 15 I'd expect hence that this should work, too: > library( Biobase ) > adf1 <- new( "AnnotatedDataFrame", df1 ) > adf2 <- new( "AnnotatedDataFrame", df2 ) > cbind( adf1, adf2 ) adf1 adf2 [1,] ? ? Is there maybe something else defined? Thanks.

in man page for AnnotatedDataFrame-class: combine is used; cbind is perhaps too suggestive for this more complex structure On Thu, Oct 21, 2010 at 12:01 PM, Simon Anders <anders at="" embl.de=""> wrote: > Hi > > I've got two objects of class AnnotatedDataFrame and would like to combine > them in the style of 'cbind'.
