# An example based on http://shiny.rstudio.com/articles/dynamic-ui.html

library(shiny)

ui = basicPage(
  fluidRow(
    actionButton(inputId = "add_buttons", label = "Add 5 Buttons")
  ),
  uiOutput("more_buttons") # this is where the dynamically added buttons will go
)

If you have a huge repository (in size and in history) and want to add a subfolder 
to your project as a submodule you can follow this example to save time and space
using git's shallow clone and shallow checkout feature. It is a bit more complicated
in this example because I assume that you want your submodule to track a non-default
branch, called `mybranch`, instead of the `master` branch. Things could probably get
a lot simpler when using the default branch. After following the commands in these
examples you can use `git submodule update` and `git submodule update --remote` as normal.

Here is an attempt at working around adding .git into dockers accidentally, an issue you saw earlier.

Docker is written in go and supports some wildcards in the ADD command. https://stackoverflow.com/questions/26591862/using-docker-add-command-for-multiples-files links to: https://golang.org/src/path/filepath/match_test.go

Putting that together,

#Taking a look at Rcssplot, seems nice enough. 
#
#Wrappers feel inelegant though, especially building commands as strings then eval(parse())
#
#here is a potential solution:
#
# 1. Build call using substitute()
# 2. get copy of property list
# 3. delete any properties that are specified by user explicitly (in ...)
# 4. append the props to the call
