[BioC] Problem with ArrayQuality Package version 1.12

Dear Agnes,

I was using your maQualityPlots code in my own function (see part of it
below). The problem seems to be that in the newer version if I load the
arrayQuality library I get an object not found error if I type gpFlagWt or
setCtlCol. When I install the old version and type them in it returns the

Could it be a difference in how it was compiled in R 2.5.1? I can run the
maQualityPlots(mrawObj) function just fine with the new version, just not as
laid out below.



fgcQualityPlots <-
function (mrawObj, mnormObj = NULL, postProcessed = FALSE, headerInfo = "",
save = TRUE, dev = "png", 
    col = NULL, badspotfunction = NULL, controlId = c("ID", "Name"), 
    DEBUG = FALSE, ...) 
require(arrayQuality, quietly=TRUE, warn.conflicts=TRUE,
require(marray, quietly=TRUE, warn.conflicts=TRUE,
if (!exists("workingDir")) {workingDir = winDialogString("Please enter the
working directory:", "D:\\Array_Experiments")}
if (!exists("prefixName")) {workingDir = winDialogString("Please enter a
Prefix Name for the experiment:", "Experiment")}
if (!exists("analysisLog")) analysisLog = FALSE;

    if (DEBUG) 
        print("function starting")
    controlId <- controlId[1]
    if (setequal(class(mrawObj), "RGList")) {  #If your data is a RGList
this function will convert it to an marray object
        mrawTmp <- as(mrawObj, "marrayRaw")
        mrawObj <- mrawTmp
    if (DEBUG) 
    for (i in 1:dim(mrawObj)[2]) {
        mraw <- mrawObj[, i]
        if(!is.null(mnormObj) & postProcessed==TRUE) {
            mnormObjTmp <- mnormObj[, i]
        opt <- list(...)

#Function to re-evaluate weights based upon flags

        if (DEBUG) 
            print("Re-evaluate Weight")
        if (missing(badspotfunction) || is.null(badspotfunction)) {
            tmp <- do.call("gpFlagWt", list(mraw at maW))
            mraw at maW <- tmp
        else if (!is.null(badspotfunction)) 
            mraw at maW <- do.call(badspotfunction, list(mraw at maW))
        ifelse(missing(col), colcode <- setCtlCol(mraw), colcode <- col)
        if (DEBUG) 
            cat("check Control color code", colcode, "\n")

Hi Peter,
I just tried to run the function meeboQuality, which calls gpFlagWt, with
the same R and BioC setting as you and it worked fine. Could you please
email me the R code you are trying to run so that I can reproduce the error?

Thank you very much,

I am running R 2.51 and Bioconductor 2.0. When I attempt to use the
arrayQuality package I get the message:

Error in do.call("gpFlagWt", list(mraw at maW)) :

        could not find function "gpFlagWt"

I installed a previous version of the package, 1.10, and it works fine as
the missing function is included with that download. Could you please update
the package or give me a solution to the problem.
