[R-SIG-Finance] Trying to plot intraday data on multiple daily plots

[Matti Zemack]

Hi all again,

Thanks Joshua, you were absolutely correct in the error you spotted.
I fixed it by inserting;
    date<-toString(datte)
before the chart_Series instruction. (See in edit to my original post below)

But I still couldn't get the plotting from chart_Series to work within the loop.

I was using chart_Series (still in alpha?) because I needed the   par(mfrow=c(5,5))   which is not available in chartSeries.
And the chart_Series gave me problems with the graphing not working in the loop…

Anyway, I decided to go the pdf-route. I instead use chartSeries with output to a pdf which is stable. And printed the pdf with 16 pages on one page. This is a perfectly working workaround waiting for a stable chart_Series.

Thanks to all package developers, all time you spent on the packages has made life much easier for me.

Regards,
Matti Zemack
