Introduction

This package allows to draw interactive charts from the JavaScript library AmCharts using Hmlwidgets.

Currently available chart types: funnel, gantt, gauge, pie, radar, serial, stock, xy.

Since it is still in developpment, some functionnalities might have an unexpected behavior. If you encounter the problem, do not hesitate to contact.

Please refer to this page http://datastorm-open.github.io/introduction_ramcharts/, you will find several examples and a quick tutorial.

Installation

The version 2.0.0 is available on CRAN:

install.packages("rAmCharts")

To install the "dev version" (v2.0.2), run the following code lines:

if (!require(devtools)) {
  install.packages("devtools")
} else {}

devtools::install_github("datastorm-open/rAmCharts")

NB:

• Version 1.1.2 is based on AmCharts v3.17.2
• Version 2.0.0 is based on AmCharts v3.18.2
• Version 2.0.2 is based on AmCharts v3.20.3

Known issues

• Problem in Shiny with Firefox (works with Chrome or Safari), the function renderAmcharts({NULL}) does not clear the chart, use conditionalPanel instead.
• Use in R Markown needs either an url path "http://www.amcharts.com/lib/3" to find images or a local path e.g. system.file("htmlwidgets/lib", package = "rAmCharts"). HTML reports also need a call to the method plot.

library(rAmCharts)
data(iris)

amHist(iris$Sepal.Length, freq = FALSE, breaks = 30, col = "gray",
       path = "http://www.amcharts.com/lib/3")
# path = system.file("htmlwidgets/lib", package = "rAmCharts"))

• Usual R colors work (for instance, light or dark prefixes), however the 'export' feature needs valid CSS colors. To be sure, use hexadecimal format if you want to use the 'export' feature.
