(a) Note that it's ``plot.acf'' NOT acf.plot.
(b) This is R --- ***ANYTHING*** is possible.
(c) Create an object, say ``y'' of class ``acf'',
having components with the right names. You could
build a dummy acf object by
> dum <- acf(rnorm(100),plot=FALSE)
and the examine ``dum'' to see what it should consist of.
(d) Something like:
y <- list(acf=array(ecc,dim=c(length(ecc),1,1)),
type="correlation",
n.used=n.ecc,lag=array(0:(length(ecc)-1),
dim=c(length(ecc),1,1)),
series="ecc",snames=NULL)
class(y) <- "acf"
plot(y)
where ``ecc'' is a vector comprising your ``externally
created correlogram'' and ``n.ecc'' is the length of the series
from which ecc was created. Note that the first entry of ecc
should be 1; it corresponds to lag 0.
