Group panels hierarchically about trelliscope HOT 4 CLOSED

Great idea - this is actually exactly how I had envisioned "implementing" such a feature - just waiting for someone to need it :). I'll relax the regex checking on group to allow / (first thing Monday) and once that is done, you can go ahead and start using / in your group specifications - of course it won't mean anything until I update the UI to deal with it, but once I do you won't have to make any changes.

I'll have to think about the best way to update the UI. A collapsible interface could get tedious for deep hierarchies. Also, what is uncollapsed by default, etc.

That sounds great. I'll be able to define the group organization.

Your point about tediousness is good. One thing to note is that the last level of my hierarchies tend to be displays based on different parameter values (quantiles in my case). In shiny, I would have handled this with a slider. In the current version of trelliscope the display window I have each as a different display. I'm not sure what's the most effective.

I've committed this change.

For what you are doing, if you are making a plot against the same data set but with different quantile parameters, and each display is a single panel, you probably want to think about creating a single multi-panel display across all quantile parameters. What you would do is basically create a ddo whose values are the quantile parameters, then make your panel function use this value to make the plot with the desired quantile setting.

For example, suppose you want quantiles from min to max in increments of 0.05 - then one way to do it is:

quantileParams <- ddo(lapply(0:20, function(x) list(x, x/20)))
panelFn <- function(q) {
  # plot function that uses the quantile value q
  # ...
}
cogFn <- function(q) {
  list(quantile = cog(q))
}
makeDisplay(quantileParams, panelFn = panelFn, cogFn = cogFn)

quantileParams is a ddo of key-value pairs, the keys are 0, ..., 20, the values are 0, 0.05, etc.

Now you have a single display with a cognostic called "quantile" and you can sort or filter your panels by this value.

OK, thanks this is helpful.
