Hello,
I need to plot a line graph using lattice so that the endpoints are
flush with the left and right vertical axes.
So the scale end points and horizontal axes length should coincide.
This works
u=newdata[1:100,] #u[,1] is from 1700-1795
xyplot(u[,2]~u[,1],xlim=range(u[,1]))
Now u[,3] is a categorical variable and now I want use u[,3] as a
conditioning variable yet still plot with the above condition
sc <- list()
sc$"x"=list(relation="free",tick.number=6)
p1=u[u[,3]==1,1]
p2=u[u[,3]==2,1]
xlim=list(range(p1),range(p2))
xyplot(u[,2]~u[,1]|u[,3],scales=sc,xlim=xlim,type="l",layout=c(1,2))
In this case there is some padding between the endpoints and the
vertical axes.
How can I remove this padding?
Many thanks
