Dear all,
I have a similar problem to this poster here:
http://grokbase.com/t/r/bioc-devel/141cegqvpf/no-method-for-coercing-
this-s4-class-to-a-vector
The error message is:
Error in as.vector(x) : no method for coercing this S4 class to a
vector
In my case, however, I'm using the as.data.frame function on a GRanges
object. When I source my function it works fine, but when I make it
into a package and then run the function I get the S4 class error.
The function seems to be from BiocGenerics:
> as.data.frame
standardGeneric for "as.data.frame" defined from package
"BiocGenerics"
function (x, row.names = NULL, optional = FALSE, ...)
standardGeneric("as.data.frame")
<environment: 0x3801ad8="">
Methods may be defined for arguments: x
Use showMethods("as.data.frame") for currently available ones.
So, I have included this
importFrom("BiocGenerics", as.data.frame)
in NAMESPACE
and this
Depends: BiocGenerics
in DESCRIPTION.
It still does not work. I must be missing something.
Any help is highly appreciated!
Thanks
Ninni
