Could not run example code given in 'rCharts: Highcharts example'

[ghost]

Hi all,

I was trying to replicate the example given here: http://rstudio-pubs-static.s3.amazonaws.com/5548_c3b680696b084e5db17eecf8c079a3c1.html

However could not run that at all. Below is the situation what happened:

library(rCharts)

Prepare data

x <- data.frame(USPersonalExpenditure)
colnames(x) <- substr(colnames(x), 2, 5)

Create chart

a <- rCharts:::Highchart$new()
Error in get(name, envir = asNamespace(pkg), inherits = FALSE) :
object 'Highchart' not found

Next I tried with this:

a <- rCharts:::Highcharts$new()

However now I got following error:

a$chart(type = "column")
a$title(text = "US Personal Expenditure")
a$xAxis(categories = rownames(x))
a$yAxis(title = list(text = "Billions of dollars"))
a$data(x)

Print chart

a$printChart()
Error in envRefInferField(x, what, getClass(class(x)), selfEnv) :
‘printChart’ is not a valid field or method name for reference class “Highcharts”

I would really appreciate if someone points me how to run them correctly.

I also want Horizontal plot, not Vertical plot as given in that example. Can someone tell me about the adjustment, if any?

Thanks and regards,

Same happened to me and for your first question I found the reason: It's a typo in the demo-code, should be Highchart_s_ instead of Highchart

a <- rCharts:::Highcharts$new()

Your second question could be solved with print instead of printChart

a$print('chart 1', include_assets = TRUE)

See here for other chart-types from Highcharts

The chart you see was made with a really old version of rCharts. We have made lot of changes to the API since then. The answers by @tinu-schneider should help you correct your code.
