I am trying to reproduce simple example with rCharts library to plot sankey chart. I found this example from scratch and tried to reproduce it, however, I came up with some problems.
Firstly I have tried running this code without nothing. Then I found out and realized, that I need d3_sankey in my computer. So, I have downloaded it from here and copied to C:\Users\adomas\Documents\R\win-library\3.0\rCharts\libraries\widgets\d3_sankey.
Then I've tried that unchanged code once more and still got the following error:
Error in file(con, "r") : cannot open the connection
In addition: Warning message:
In file(con, "r") :
cannot open file '/config.yml': No such file or directory
Since that didn't help too, I have tried changing paths from:
sankeyPlot$setLib('libraries/widgets/d3_sankey')
sankeyPlot$setTemplate(script = "libraries/widgets/d3_sankey/layouts/chart.html")
to
sankeyPlot$setLib('C:/Users/adomas/Documents/R/win-library/3.0/rCharts/libraries/widgets/d3_sankey')
sankeyPlot$setTemplate(script = "C:/Users/adomas/Documents/R/win-library/3.0/rCharts/libraries/widgets/d3_sankey/layouts/chart.html")
However, this time, the blank screen in Viewer appeared but no actual Sankey graph and I got the following in console:
Warning message:
In readLines(file, warn = warn, ...) :
invalid input found on input connection 'C:/Users/adomas/Documents/R/win-library/3.0/rCharts/libraries/widgets/d3_sankey/layouts/chart.html
I have tried changing paths and etc, but still something is wrong. And I am not sure if I need to use sankeyPlot$setTemplate at all.
I want to use Sankey chart in my shiny application, but firstly I want to reproduce simply in R. Suggestions would help a lot!
Versions of libraries:
rCharts_0.4.2
igraph_0.7.0
R version: 3.0.2
EDITED: I have tried this code on different system. And everything works there. Versions of libraries and R are the same and I've copied same documents and just specified full path. I have tried that again on my own computer, but still got the same error yet.
