plotting a Grouped Data object

[Karin <twentestat@yahoo.com>]

Hello,

 

I am trying to plot data from a GroupedData object. I have one inner factor, named factor1, so I want for all subjects a plot with two lines in it (for each level of the inner factor one).

I thought that is automaticaly should plot the two lines with different styles (e.g. lty=1 and lty=2). However that is  not the case.

What do I have to add to plot two lines with different styles?

 

The commands till so far are:

 

temp<-groupedData(y~x|subject,data="">

plot(temp,inner=~factor1,ylab="y",xlab="Part",ylim=c(0,4.5))

 

Thanks in advance,

 

Karin
