Issues installing Plotly Dash for R


Issues installing Plotly Dash for R

Hope that helps Just installed the package to reproduce the error, unfortunately can't be able to reproduce it. However, a potential solution along "error 403 and API rate limit exceeded ..." could be to add your github authorization token in your .Rprofile and that is what the "But here's the good news:" message inside the bracket is trying to inform you. Have a look at the actual project github site Dash for R if you haven't already. That might as well provide you an input to solving the issue.

I hope this helps you . According to this plotly documentation you need to register any new language first.
In your case this means you need to add

help you fix your problem It seems that RangeSlider can't work directly with Timestamp objects. You need to convert them into numerical (POSIX) timestamps to work with the slider, and convert them again into objects inside the callback function.
The following worked for me:
code :
import dash
import dash_core_components as dcc
import dash_html_components as html
import numpy as np
import pandas as pd

external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']

# Demo dataframe with a 'date' column
df = pd.DataFrame({'date': pd.to_datetime(np.linspace(1500000000, 1550000000, 9), unit='s')})

app = dash.Dash(__name__, external_stylesheets=external_stylesheets)
app.layout = html.Div([
    dcc.RangeSlider(
        id='slider',
        min=df['date'].min().timestamp(),
        max=df['date'].max().timestamp(),
        value=[df['date'].min().timestamp(), df['date'].max().timestamp()],
    ),
    html.Div(id='slider-container')
])


@app.callback(
    dash.dependencies.Output('slider-container', 'children'),
    [dash.dependencies.Input('slider', 'value')])
def update_output(value):
    if value:
        return 'You have selected "{}"'.format(list(pd.to_datetime(value, unit='s')))

help you fix your problem This is an inelegant workaround, but after scouring the plotly python docs, I couldn't find anything that would do exactly what you were asking with the plotly attributes provided. If you need a one-time, quick fix now, try using yaxis=dict(showticklabels=False) and add your labels manually as annotations like:
code :
layout = go.Layout(
    # Hide the y tick labels
        yaxis=dict(
        showticklabels=False),
    annotations=[
        dict(
        # I had to try different x values to get alignment
            x=0.8,
            y='giraffes',
            xref='x',
            yref='y',
            text='Giraffes',
            font=dict(
                family='Arial',
                size=24,
                color='rgba(255, 255, 255)'
            ),
            align='left',
        # Don't show any arrow
            showarrow=False,
        ), 
app.layout = html.Div([
  html.Div([ 
    html.Div([
        dcc.Graph(id = 'age',
                          figure = {
                                    'data': [go.Bar(x = values1,

                                                    text = labels1,

I wish this helpful for you Your y-coordinates have the wrong format. I suggest you flatten them in your scatter creation, so you change:
code :
y=y_data
y=y_data.flatten()
y=regr.predict(x_data)
y=regr.predict(x_data).flatten()

With these it helps When trying to install the Dash package using both pip and conda, I am getting an error saying that the package cannot be found. All other packages install fine with pip , You can install it via:
code :
conda install -c conda-forge dash
