Hi,
I am having trouble plotting the graph I need given the follow kind of data
> xxx <- data.frame(
"x"=c(1,2,3,4,5),
"y1"=c(2,4,3,5,6),
"y2"=c(3,4,6,3,1),
"y3"=c(1,3,5,7,3),
"z1"=c(1,NA,3,5,NA),
"z2"=c(2,NA,4,6,NA) )
> xxx
x y1 y2 y3 z1 z2
1 1 2 3 1 1 2
2 2 4 4 3 NA NA
3 3 3 6 5 3 4
4 4 5 3 7 5 6
5 5 6 1 3 NA NA
What I need is the following
- One graph
- y1, y2, y3 plotted as seperate lines vs x
- z1, z2 give the range of the value of z, and need to be plotted as error bars
or confidence intervals vs x
Many thanks for any help,
Regards,
David
