How to change plot size?
options(repr.plot.width = 4,
repr.plot.height = 3)Will you support %%cell magic?
We don’t and won’t support %%cell magic like %%HTML.
You can use IRdisplay::display_html() and other IRdisplay functions instead.
I use SVG as plot mimetype. My browser became slow after I displayed too many data points. Help?
Due to overplotting, displaying many points will reduce the interpretability of the plots. Consider using smoothScatter().
If you use ggplot2, you’ll want (stat|geom)_density_2d() or (stat_bin|geom)_hex().
Why is some error message shown in the kernel log, not the cell output?
It’s probably a library writing to stderr on a low level. Watch this issue if it affects you.
Why do I get kernel crashes with ?
You probably had pbdZMQ compiled against a different R version. Try reinstalling it!
Why doesn’t only the value of a cell’s last statement appear, like in IPython?
R is more of a functional language than Python (e.g. you need no return statements), and has an explicit visibility modifier via invisible(value).
Examples:
'Displayed'
{
'Not displayed'
IRdisplay::display('Displayed via the display system')
'Displayed, because the block evaluates to this value'
}
invisible('Not displayed')
