[Request] Provide a parameter to suppress the "No trace type specified" warning+message

[daattali]

For example, the first sample code in ?plot_ly is

plot_ly(economics, x = ~pop)

Running that results in

No trace type specified:
  Based on info supplied, a 'histogram' trace seems appropriate.
  Read more about this trace type -> https://plot.ly/r/reference/#histogram

Sometimes this comes out as a warning and sometimes as a message. There are a variety of ways to deal with workarounds trying to suppress warnings/messages they're not ideal. It would be great if there was a parameter that would allow us to suppress such messages

I'm curious, @daattali : how do you hid the output? I haven't found a way to suppress this message

[cpsievert]

Note that the No trace type specified: message can be suppressed by being more deliberate about what trace type is used:

plot_ly(economics, x = ~pop, type = "histogram")

Most plotly messages and warnings happen at print time, so if you want/need a more general way to suppress this (or other) messages (or warnings), you'll have to wrap a call to plotly_build():

suppressPlotlyMessage <- function(p) {
  suppressMessages(plotly_build(p))
}

suppressPlotlyMessage(plot_ly(economics, x = ~pop))
