[BioC] maBoxplot in v1.4

[charles.edwin.white at us.army.mil]

PrintTip boxplots fail with the following error message under R 1.9.0 and Bioconductor v1.4:
“Error in boxplot.default(yy ~ xx, xlab = "PrintTip", ylab = "M", names = c("(1,1)",  : 
	names attribute [16] must be the same length as the vector [1]”

The exact same test code works fine under R 1.8.1 (… and whatever version of Bioconductor I’m running there …).

library(marrayInput)
swirl.layout <- read.marrayLayout(fname = "fish.gal", ngr = 4, ngc = 4, nsr = 22,
                                  nsc = 24, skip = 21,ctl.col = 4)
ctl <- rep("Control", maNspots(swirl.layout))
ctl[maControls(swirl.layout) != "control"] <- "N"
maControls(swirl.layout) <- factor(ctl)
swirl.targets <- read.marrayInfo("SwirlSample.txt")
swirl.gnames <- read.marrayInfo("fish.gal",info.id = 4:5, labels = 5, skip = 21)
datadir <- getwd()
fnames <- dir(path=datadir,pattern=paste("*", "spot", sep="\."))
swirl<- read.Spot(fnames, path=datadir,
                  layout = swirl.layout,
                  gnames = swirl.gnames,
                  targets = swirl.targets)
library(marrayPlots)
maBoxplot(swirl[, 1])

Help would be appreciated. Thanks!
