[BioC] duplicateCor

[Houeix, Benoit]

Hi all, i was wondering if anyone could help mw.
I am trying to calculate the correlation between two replicates spots.
I triied following the manual and the bioC website but have not managed to understand
why it is not working for me.
I got this message :

> cor <- duplicateCorrelation(RG, design, ndups=2, spacing=5376)
Error in dim(M) <- c(spacing, ndups, ngroups, nslides) :
        dim<- : dims [product 86016] do not match the length of object [87552]

thank you to help.
