4 arguments passed to .Internal(nchar)

jwang-lilly commented 8 years ago

Dear rAmCharts developer: (this issue is also submitted to https://github.com/DataKnowledge/rAmCharts/issues/1 While running the demo example from rAmCharts shiny, I encountered this error: 4 arguments passed to .Internal(nchar) which requires 3

According to google, this may have something to do with the version of R I have.

I just want to confirm with you. Is there any solution to avoid this error while using R 3.2.0?

Thanks,

-Jian Wang

Shiny code

library(shiny)
library(rAmCharts)

ui = fluidPage(amChartsOutput(outputId = "amchart"))

server = function(input, output) {
output$amchart <- renderAmCharts({
# minimal example
iris <- get(x = "iris", pos = "package:datasets")

amBoxplot(iris[, -5])
})
}

shinyApp(ui = ui, server = server)

Hi,

As you says and you read, there is a little bug with R 3.2.0 or older. nchar function seems to be modified in 3.2.1, and so we observe bad interaction with a lot of packages....

The best way to solve that is to update R if you can....

Hi,

Thanks much for the advice.

May I take this opportunity to ask a related question. At rAmCharts webpage (https://github.com/datastorm-open/rAmCharts), you mentioned gantt chart is one of the chart types.

However, I couldn’t find any example for using amGannt(). Could you share with an example of using amGannt()? Thanks much.

-Jian
