How to store specific data in checkboxInput and get the data from it?

[Thiam Kok Lau]

I don't understand how checkboxInput() works in Shiny. For instance, I want to create a checkbox input with some data in it,

`<input type="checkbox" id="species" name="species_particles" value="nox"/>`

But all I can do with Shiny is,

```

checkboxInput(inputId = "species",

                    label = "PM 2.5 particulates ug/m3",

                    value = FALSE)

```

Where can I store `value="nox"` and `name="species_particles"`??

And the most important - how can I get this data in `server.R`?

in my server.R, I have this `species = input$species` and of course I only get this data - `FALSE`

What can I do?

Maybe you want checkboxGroupInput: http://shiny.rstudio.com/reference/shiny/latest/checkboxGroupInput.html
