Slicer -- min and max issues (Need indexes?)

[TahiriNadia]

In Python version:

Code:

import dash_core_components as dcc

dcc.RangeSlider(
    marks={i: 'Label {}'.format(i) for i in range(-5, 7)},
    min=-5,
    max=6,
    value=[-3, 4]
)

Result:

In R version:

Code:

library(dashCoreComponents)

dccRangeSlider(
    marks=c(paste("Label", -5:6)),
    min=-5,
    max=6,
    value=list(-3, 4)
)

Result:

c(paste("Label", -5:6)) doesn't look like the R equivalent of
{i: 'Label {}'.format(i) for i in range(-5, 7)}

I think you need something like list('-5'='label -5', '-4'='label -4', ...) instead. Perhaps:
setNames(c(paste("Label", -5:6)), -5:6)?

That said the fact that we'll render labels beyond the range of the slider seems like a bug - @TahiriNadia would you mind making an issue for this over at https://github.com/plotly/dash-core-components/issues?

Nice! The latter snippet worked for me.

@TahiriNadia As @alexcjohnson noted, the label rendering problem is a dash-core-components problem rather than something to fix in DashR, but we should open an issue for this there anyway.

If this resolves your problem, feel free to close the issue 🙂

Thank you @alexcjohnson for your ideas. I tried and gave some modifications to convert into a list, here my code:

Code:

dccRangeSlider(
    marks=as.list(setNames(c(paste("Label", -5:6)), -5:6)),
    min=-5,
    max=6,
    value=list(-3, 4)
)

Result:
