I've got 30 chips, 5 controls and 5 chips x5 treatment groups and decided that LIMMA would be the best to analyze these data.
I am using this package for the first time (downloaded and installed today, March 16 2004) and I am thus following the manual instructions. But Alas!
I've got the following error message:
fit2 < eBayes(fit2)
coefficients stdev.unscaled sigma df.residual method design contrasts
TRUE TRUE FALSE TRUE FALSE TRUE FALSE
df.prior s2.prior var.prior proportion s2.post t p.value
FALSE FALSE FALSE FALSE TRUE TRUE FALSE
longer object length is not a multiple of shorter object length in: fit2 < eBayes(fit2).
Because of this error, no information is extractable afterwards and obviously I get further error messages:
Error in array(x, c(length(x), 1), if (!is.null(names(x))) list(names(x), :
attempt to set an attribute on NULL
> clas <-classifyTests(fit2)
Error in classifyTests(fit2) : tstat cannot be extracted from object
Any idea of what went wrong?
Thank you very much for any suggestions!
