Dear Joris,
Thank for your comments. Changing importFrom("zoo", rollmax) to
importFrom("zoo", rollmax, rollmax.default) solved the problem.
Best regards,

To call in the statistician after the experiment is done may be no more than
asking him to perform a post-mortem examination: he may be able to say what the
experiment died of.

Onderwerp: Re: [Rd] incorrect import?
'rollmax' is a generic S3 method, and the point of that is to be visible to the
user. If you only import the generic, it can't find the methods as they still
reside in the namespace of 'zoo', which you neither imported nor attached to
the search path. So either you import also the relevant methods, or you just
load the zoo package using Depends instead of Imports and import.
Cheers
Joris

Dear all,
I'm not getting what I'm doing wrong. The line below from my read.fsa.bin
function throws an error when just loading my AFLP package and disappears when
I load the zoo package as well.
#the line that throws the error
Index <- which(Peak == rollmax(Peak, k = 1 + 2 * floor((min(diff(SizeStandard))
* Fs - 1) / 2), fill = -Inf))
#the error
Error in UseMethod("rollmax") : no applicable method for 'rollmax' applied to
an object of class "c('double', 'numeric')"
DESCRIPTION of the AFLP package contains
Imports: ggplot2, mvtnorm, seqinr, zoo, signal, xtable, vegan
The NAMESPACE contains
importFrom("zoo", rollmax)
What am I missing?
