问题
For this question, I am using the R Shiny tutorial example found here:
http://rstudio.github.io/shiny/tutorial/#datatables
Running the code on this tutorial renders the application at the following URL
http://glimmer.rstudio.com/yihui/12_datatables/
What I would like to know is, once that data table is rendered, we can search it using the functionality built into the renderDataTable() function in R Shiny, but is it possible to download the data you have filtered to using the renderDataTable() function?
For instance, if in the data table search bar I type, "Very Good," only the records in the "cut" field which read "Very Good" are displayed. How would I then download that data set?
How would I invoke the TableTools.js copy, print, save, etc buttons into this code?
Thank you!

You need to link to the correct library versions. Links to data.table 1.9.4 can be found at http://cdnjs.com/libraries/datatables . Links to tabletools 2.1.5 at http://cdnjs.com/libraries/datatables-tabletools
library(shiny)
library(ggplot2)
runApp(
list(ui = basicPage(
h1('Diamonds DataTable with TableTools'),
tagList(
singleton(tags$head(tags$script(src='//cdnjs.cloudflare.com/ajax/libs/datatables/1.9.4/jquery.dataTables.min.js',type='text/javascript'))),
singleton(tags$head(tags$script(src='//cdnjs.cloudflare.com/ajax/libs/datatables-tabletools/2.1.5/js/TableTools.min.js',type='text/javascript'))),

),
dataTableOutput("mytable")
