[BioC] error msg w/ read.marrayRaw() : "targets" matched by multiple actual arguments

[Ken Termiso]

Hi all,

When loading cDNA data using read.marrayRaw(), everything works fine until I 
specify an marrayInfo object as targets parameter of read.marrayRaw()

i.e.

files_s <- c("slide_63_trunc.csv", "slide_64_trunc.csv", 
"slide_65_trunc.csv", "slide_72_trunc.csv")
>maraw <- read.marrayRaw(fnames = files_s, name.Gf = "Ch1 Mean", name.Gb = 
>"Ch1 B Mean", name.Rf = "Ch2 Mean", name.Rb = "Ch2 B Mean", name.W = NULL, 
>layout = NULL, gnames = NULL, targets = NULL, notes = NULL, sep = ",")
Reading ...  ./slide_63_trunc.csv
Reading ...  ./slide_64_trunc.csv
Reading ...  ./slide_65_trunc.csv
Reading ...  ./slide_72_trunc.csv
Warning message:
incomplete final line found by readLines on `./slide_63_trunc.csv'



..specifying a targets file (which i adapted as a test from the swirl data 
in marray package) :

s.targets <- read.marrayInfo(fname = "SSample.txt")

s.targets
An object of class "marrayInfo"

now specifying an marrayInfo object with read.marrayRaw() :

maraw2 <- read.marrayRaw(fnames = files_s, name.Gf = "Ch1 Mean", name.Gb = 
"Ch1 B Mean", name.Rf = "Ch2 Mean", name.Rb = "Ch2 B Mean", name.W = NULL, 
layout = NULL, gnames = NULL, targets = NULL, notes = NULL, sep = ",", 
targets = s.targets)
Error in read.marrayRaw(fnames = files_s, name.Gf = "Ch1 Mean", name.Gb = 
"Ch1 B Mean",  :
	formal argument "targets" matched by multiple actual arguments

Not sure what's happening here. I've got :

OS X 10.3.9
R 2.0.1 for Aqua GUI
marray 1.5.30


Thanks in advance for any help,
Ken
