Basic Example
library(plotly)
fig <- plot_ly(
type = 'scatter',
x = mtcars$hp,
y = mtcars$qsec,
text = paste("Make: ", rownames(mtcars),
"<br>hp: ", mtcars$hp,
"<br>qsec: ", mtcars$qsec,
"<br>Cyl: ", mtcars$cyl),
hoverinfo = 'text',
mode = 'markers',
transforms = list(
list(
type = 'groupby',
groups = mtcars$cyl,
styles = list(
list(target = 4, value = list(marker =list(color = 'blue'))),
list(target = 6, value = list(marker =list(color = 'red'))),
list(target = 8, value = list(marker =list(color = 'black')))

What About Dash?
Dash for R is an open-source framework for building analytical applications, with no Javascript required, and it is tightly integrated with the Plotly graphing library.
Learn about how to install Dash for R at https://dashr.plot.ly/installation.
Everywhere in this page that you see fig
, you can display the same figure in a Dash for R application by passing it to the figure
argument of the Graph
component from the built-in dashCoreComponents
package like this:
library(plotly)
fig <- plot_ly()
# fig <- fig %>% add_trace( ... )
# fig <- fig %>% layout( ... )
library(dash)
library(dashCoreComponents)
library(dashHtmlComponents)
app <- Dash$new()
app$layout(
htmlDiv(
list(
dccGraph(figure=fig)
)
)
)
app$run_server(debug=TRUE, dev_tools_hot_reload=FALSE)
