R help - Aug 2016 - RDCOMclient copy excel chart to powerpoint

Hello,

I'm currently working on a project that requires me to create charts in
excel
and copy them to a powerpoint presentation. I've been using the RDCOMclient
package to build the charts in excel. I'm now working on actually moving the
charts from excel to powerpoint and I can't seem to figure it out. I've
included some code below (excluding the function that actually creates the
chart as that actually works).

I know that there are better ways to create presentations (ggplot2 and
ReporteRs or just markdown) but the project has some specific requirements
that are met through this method.

library(RDCOMclient)

# Connect and create workbook/presentation
excel.connect      <- COMCreate("Excel.Application")
powerpoint.connect <- COMCreate("Powerpoint.Application")

excel.workbook          <- excel.connection[["Workbooks"]]$Add()
powerpoint.presentation <-
powerpoint.connection[["Presentations"]]$Add()

# Create Chart, return chart COM object
excel.chart.com <- excel.chart(data, aesthetics) # This works so i'm not
                                                                      #
including the code
                                                                      #
Also creates a new sheet

# Move to powerpoint
excel.to.powerpoint <- function(chart.com,
                                excel.connect,
powerpoint.connect) {
    # Create Slide
    powerpoint.slide <- powerpoint.connect[["Slides"]]$Add(1,12)

    # Copy Chart
    chart.com$Copy()

    # Select Slide
    powerpoint.slide$Select()

    # Paste
    # I've tried a few things here (not all listed) including:
    chart.com$Paste()
    powerpoint.slide$Paste()
    # But I cant seem to get it to work.

}

Does anyone have any suggestions?

Thank you,
Patrick Doelp
