Hi,
Am I using the right versions of arrayQuality and hexbin in BioC 1.6?
Package: arrayQuality
Version: 1.0.11
Date: 2005-04-10
Package: hexbin
Version: 1.2.7
Date: 2005-04-06
Working through the 'Quick start guide for marray' I ran into a
problem
in step 6 [ library(arrayQuality); maQualityPlots(mraw) ]:
Error in seq.default(0, 1, length = min(17, maxcnt)) :
length must be non-negative number
In addition: Warning message:
no finite arguments to max; returning -Inf
Traceback shows it is in qpHexbin and looking at the function and
documentation shows bin is an S4 object of class hexbin and mac$cnt
this cannot access the slot 'count'. After fixing that, it runs into:
Error in qpHexbin(mnorm, main = "MA-Plot :: Norm") :
couldn't find function "hexagons"
Error in qpHexbin(mnorm, main = "MA-Plot :: Norm") :
couldn't find function "hex.legend"
Which I also changed as in below file qpHexbin.R. The library version
I've
renamed qpHexbin-orig.R.
