[Bioc-devel] Vignette package error

[Jason Ross]

Hi,

My recently submitted package is failing with this error:
"Error: processing vignette 'IntroductionToHarman.Rmd' failed with 
diagnostics: there is no package called 'missMethyl'
Execution halted"

Build report here: 
http://bioconductor.org/spb_reports/Harman_0.99.1_buildreport_20160202233741.html

However, missMethyl has been in Bioconductor since 3.0.
See: https://www.bioconductor.org/packages/release/bioc/html/missMethyl.html

I'm not sure what I'm doing wrong? Is the build environment rather old? 
Should I have missMethyl in the 'suggests' field in the DESCRIPTION file?

Regards,
Jason.
