Familty 'sans' not included in postscript() device

[IanSudbery]

I got a new error I've not seen before in my report. It's from a rather complicated user renderer, actaully something I was working on as a possible tracker plugin. The tracker creates plots using the Gviz genomic visualisaiton library in R. The error is:

CGATReportError

        stage: collection
        exception: rpy2.rinterface.RRuntimeError
        message: Error in grid.Call.graphics(L_text, as.graphicsAnnot(x$label), x$x, x$y, :

        traceback:

I assume that this happens when CGATReprort is trying to save the user generated plot as an eps file, and it contains a font that isn't availible.

You can see this for yourself by running the CircularCandidates tracker in the CircularCandidates module in project 28 (for e.g. /ifs/projects/proj028/project_pipeline_full2).
