[BioC] ReadAffy and hist() labels

[Hrishikesh Deshmukh]

Hi All,

I want the CEL file names to be displayed, i have
truncated file names which were long but still i can't
see all the file names on the boxplot().

Here is the script which i have written,i tried
attaching postscript files but since they were big, i
am not attaching them here.

library(affy)
library(hgu95av2cdf)
library(hgu95av2probe)
library(matchprobes)
data(hgu95av2probe)
summary(hgu95av2probe)
getwd()
setwd("C:/Program Files/R/rw2001/Normal")
Data <- ReadAffy()
length(Data)
hist(Data)
boxplot(Data)
> boxplot(Data,xlab=sampleNames)
Error in title(main = "", xlab = function (object)  : 
        cannot coerce type closure to character vector
> hist(Data,xlab=sampleNames)
Error in title(main = main, sub = sub, xlab = xlab,
ylab = ylab, ...) : 
        cannot coerce type closure to character vector

Thanks in advance.
