Constrain Numeric Input To Be Non-Negative

[kpivert]

Description

Thank you again for surveydown. Is there a way to constrain numeric input questions to 0 or above? After reading your documentation, I tried passing the min = 0 argument for shiny::numericInput() (I'm assuming that is what's under the hood?) to the options argument (realizing that's not what options are for).

(Apologies if I missed this in another thread. I searched using numeric.)

Package Version: 1.0.2
OS: Windows 11
R Version: 4.5.1

Thanks very much,

Kurtis

Actually right now we're just using shiny::textInput() for numeric question types: https://github.com/surveydown-dev/surveydown/blob/main/R/ui.R#L1024-L1029

I'm not sure why we did that, we probably had a reason. But it allows any input type, so that seems like a silly choice. Changing that to shiny::numericInput() is probably a good idea.

Got it. Thanks again, John.

After a little more discussion, one of the reasons we use shiny::textInput() instead of shiny::numericInput() is that there are a lot of types of numeric things that don't work well, like zip codes. For example, 01234 can't be entered with shiny::numericInput(). So we use the text input with some customized code to make it work like numbers, but it's more flexible. We could potentially add some min argument like you suggested, but it'd be a custom implementation.

Thanks again, John. That makes perfect sense (for zip codes or FIPS). FWIW, my use case is asking about numbers of physicians and APPs at an institution, so I was trying to prevent any erroneous responses if participants accidentally hit the down arrow. I'll switch this to slider_numeric for this implementation. A custom implementation isn't warranted.
