Dear madam, sir,

I am using Limma with the latest version of bioconductor.

After succesfull loading of my Imagene files I want to load a file called
SpotTypes.txt as outlined in the Limma usermanual on page 6.
Reading the spottypes goes well, but when I apply the spotStatus function I
get the following error message:

	> RG$genes$Status <- spotStatus(spottypes)
	Error: couldn't find function "spotStatus"

If I leave out the spottypes I can create MA plots etc.
I'm rather new to R so sometimes I'm puzzled if it is something I do wrong
or if something is broken in the package.
Could you tell me if this is a bug in Limma or if it is my fault.

This is the order of things I do. I attached the SpotTypes.txt file
--------------------------------
library(limma)
files<-cbind("cy3.tab.txt","cy5.tab.txt")


#read the imagene files
RG <- read.imagene(files)

#set the spottypes
spottypes <- readSpotTypes()

RG$genes$status <- spotStatus(spottypes) # this goes wrong
------------------------------------


best regards
