[BioC] pmStrand() in oligo (version...)

[De Bondt, An-7114 [PRDBE]]

Hi Ben, 

When using oligo version 1.0.2-3, the pmStrand function indeed works :-) 
but the snprma function results in an error:

     fsetSty <- read.celfiles(dir()[grep("S.CEL", dir())])
     rmaSty <- snprma(fsetSty)

Normalizing...Error in readChar(con, 5) : cannot open the connection
In addition: Warning message:
cannot open compressed file

How can I check which connection needs to be established?

Thanks in advance for your help!
An

Hi An,

I fixed that problem, thanks for the report.

Also, regarding the .crlmm.regions packages, these are not anymore  
required.

If you use the following version instead (which should appear soon on  
BioC), these problems should be taken care of:

Thank you,
