dev Cairo (capital C) options no longer working because package cairoDevice is archived

[jessekps]

A minor issue:

opts$chunk_est(dev="Cairo_pdf")

is no longer working because package cairoDevice is no longer available on CRAN. All the options with lower case C are still working, so you might consider omitting these.

caused by these lines in plot.R

    Cairo_pdf = load_device('Cairo_pdf', 'cairoDevice'),
    Cairo_png = load_device('Cairo_png', 'cairoDevice'),
    Cairo_ps = load_device('Cairo_ps', 'cairoDevice'),
    Cairo_svg = load_device('Cairo_svg', 'cairoDevice'),

This still works fine since it uses just the cairo package: opts$chunk_set(dev="cairo_pdf")
