In shuttlethread/hodfr: Hands-on-Data-Frame for R

HODFR: Hands-on-dataframe Shiny adapter

A Shiny input widget using hodf, allowing collection of data.frame objects with variable column widths.

Installation

You can install directly from GitHub:

devtools::install_github('shuttlethread/hodfr')

Quick start

Somewhere in the UI definition, include a hodfr element with::

hodfr::hodfr(
    "catch_at_age",
    fields = list(type = "bins", max = 10),
    values = list(type = "year", min = 2000, max = 2010)),

...then in server.R, input$catch_at_age will be a data.frame with the contents of the table.

fields and values give a range for the data.frame rows and columns respectively. These exactly match the values for a hodf template, see the template documentation for more detail and examples.

You can also update the data.frame contents from R with:

hodfr::updateHodfrInput(session, "catch_at_age", new_data)

For a complete example, look at the demo/hodfr.R script.

HODFR Development

The package includes precompiled javascript sources, to make any changes to javascript you need to re-build this as well as the package with either make build, or make install to rebuild and install the built R package.
