Accessing a library's function via the double colon operator doesn't seem to work.
I am attempting to use the SCAN.UPC(http://bioconductor.org/packages/release/bioc/html/SCAN.UPC.html) library via rpy2. If I try to call one of its functions using the double colon operator like so:
ro.r["SCAN.UPC::SCANfast"]( raw_file, processed_file )
I get the error:
LookupError: 'SCAN.UPC::SCANfast' not found
However if I load the library via the
library function first and then call the function I want to use like so:
ro.r("library('SCAN.UPC')") ro.r["SCANfast"]( raw_file, processed_file )
it works. Is there any way this could be supported? It's definitely not a major issue but my understanding is that using the double colon operator is a best practice for R code. Perhaps there's a way to actually do it but searching on both google and stackoverflow didn't turn up any results related to rpy2 and double colon.
