[BioC] Problem with mgu74av2LOCUSID environment

It appears that your first argument (vav2onlyLI) to ll.htmlpage is a list while 
ll.htmlpage is expecting a vector. I was able to create a table with correct ids 
by unlisting vav2onlyLI (after replacing the unknow 
RES.lm[RES.lm[,"eff"]=="vav2","gene"] with a set of probe ids. It would be nice 
if you could provide example code that can be run directly next time).

>Dear all,
>I have recently changed my version of R form 1.8.1 to 1.9.0.
>I have been trying to produce a few html pages with some of my results
>and up to now I have had no problems. See below:
>Locus ID  Gene Symbol  Affy ID  Pvalue  FC  
>17865  Mybl2 100023_at 0 1.68 
>12035  Bcat1 100026_at 0 1.58 
>22271  Upp1 100030_at 0 1.54
>Where the first column is a hyperlink to LocusLink obtained with the
>following piece of code:
> vav2onlyNames <- RES.lm[RES.lm[,"eff"]=="vav2","gene"]
> vav2onlyLI <- multiget(vav2onlyNames, env = mgu74av2LOCUSID)
> vav2onlySYM <- multiget(vav2onlyNames, env = mgu74av2SYMBOL)
> vav2onlyRes <- data.frame (unlist(vav2onlySYM))
>ll.htmlpage(vav2onlyLI, filename = "Vav2 genes.html", 
>	        title = "Vav2 genes", othernames =
>                                               c("FC","Pval")]), 
>		  table.head = c("Locus ID", "Gene Symbol", "Affy ID",
>"FC","Pval",), table.center = TRUE)
>The problem has begun when I have started using the R version 1.9.0.
>Instead of the html table format I have detailed before - and using the
>exact same code, I obtain the following:
>Locus ID  Gene Symbol  Affy ID  Pval FC    
>as.integer(17865)  Mybl2 100023_at 0 1.68
>as.integer(12035)  Bcat1 100026_at 0 1.58
>as.integer(22271)  Upp1 100030_at 0 1.54
>where the first column stops being a useful LocusLink hyperlink.
>I am not totally sure this is the correct list to share my concerns, if
>not, I apologize in advance and I hope someone can give me an idea of
>what is going on or direct me to the appropriate place where I could
>receive help.
