Dynamic input and output

[Winston Chang]

Hi everyone -

Someone recently asked me about creating a dynamic number of inputs in Shiny, so I wrote an example and I thought I'd share. This one actually has a dynamic number of inputs and outputs:

Thanks. What is the local() function please ?

[Ramnath Vaidyanathan]

From R Help

? local

local evaluates an expression in a local environment. It is equivalent to evalq except that its default argument creates a new, empty environment. This is useful to create anonymous recursive functions and as a kind of limited namespace feature since variables defined in the environment are not visible from the outside.

Ah ok Ramnath, I thought this was a Shiny specific function. 

@Winston, Let me give a link here to a similar problem: generating a dynamic number of tabpanels
