R help - Feb 2012 - R Package "example" section of .Rd file question (think it's a non-ASCII issue, but not sure...)

Hey,

I keep getting the following warning:
> data(GSE19829-GPL570_eset)
Warning in data(GSE19829 - GPL570_eset) :
  data set ‘GSE19829 - GPL570_eset’ not found
> ## maybe str(GSE19829-GPL570_eset) ; plot(GSE19829-GPL570_eset) ...
>
> if(require(affy)){
+   summary(GSE19829-GPL570_eset$vital_status)
+  }
Error in summary(GSE19829 - GPL570_eset$vital_status) :
  object 'GSE19829' not found
Execution halted

This error does not happen on other of my other .Rd files.  None of the
other .Rd files have a "-" character in their title.  for example, the
other files have the following:
>data(GSE1234)
OR
>data(GSE5678)
I think the issue is the "-" character, but I'm not sure.  Does
anyone know
if this is the case?  And if so, how do I fix it?  If not, any other
suggestions?

Much thanks!

Ben

Hi Ben --

'-' is being parsed as a minus sign;  you could (I think) quote it

   `GSE19829-GPL570_eset`

or better come up with a legal name.
