Provide better `vsc.dev.args` defaults

Open ThomasSoeiro opened this issue 2 months ago • 1 comments

Describe the bug

Plots are barely readable with default dimensions and resolution (whatever the layout).

getOption("vsc.dev.args")
# $width
# [1] 800
# 
# $height
# [1] 1200
#

To Reproduce

Create any plot, e.g.:

plot(1)

Can you fix this issue by yourself? (We appreciate the help)

Maybe.

vsc.dev.args is documented in the wiki.

I guess we need to edit:

https://github.com/REditorSupport/vscode-R/blob/61088253ee8adf32933590cd436e2bb93c6f3597/package.json#L1822-L1828

Which is applied by:

https://github.com/REditorSupport/vscode-R/blob/61088253ee8adf32933590cd436e2bb93c6f3597/R/session/vsc.R#L38

Expected behavior

Provide better default (especially 1:1 aspect ratio and higher resolution), e.g.:

This is more in line with e.g. png() et al., ggsave() defaults, or RStudio plot viewer.

Screenshots

Default:

With suggested change applied in settings.json:

    "r.plot.devArgs": {
        "width": 1200,
        "height": 1200,
        "res": 200
    }

or in .Rprofile:

options(vsc.dev.args = list(width = 1200, height = 1200, res = 200))

we get:

Additional context

I am aware of httpgd; I am suggested better defaults for the default viewer.

Thanks for this excellent extension!
