variable UI elements

[datalies]

This may be an issue, or more of a question about how to do something - it doesn't seem possible as I see it now.

I have an application that takes an input (a search term, for example), processes that input in the shinyServer() and returns output to the mainPanel().

Conceptually, I would like to further manipulate this output, by creating checkboxes/sliders/, based on the output - that can be modified, then reactively updating certain outputs. Normally (in R), I would do something like this:

for(element in as.character(elements)) {
element_id <- paste(element, 'id', sep = '_')
element_label <- paste('Change level of', element', ':')
sliderInput(element,
element_label,
value = as.numeric(outputData[element]),
min = 1,
max = 1000)
}

... this for-loop approach does not work - the only solution I have come up with is to hard-code a bunch of conditionalPanel()s, and activate the ones relevant to the given search/output in question, which compromises any sort of order I might desire to display these UI elements in.

Is there a way to deliver a variable number of UI elements based on the data held in the Output object that shinyUI() elements draw from?

BTW! ... thank you soooo much for developing this package. I have been waiting for exactly this sort of project for 3 years now. It may be new and have development to go, but what you have here is exceptional and I can't thank you enough :)

PS I have only been using this package since Sunday, so I may be missing something obvious. I'm also new to the sort of server-client communication structure (i.e., input$ and output$ vars)

ah... yes. I glossed over that section a bit - but I see how you mean now.
I will refer to the shiny-discuss group for further (non-bug) issues. Many
thanks!
