Hi List,

This is possibly a newbie error. I have however searched long and hard
and haven't found a solution.

I am attempting to plot multiple lattice graphs in R, plotting 4 per
page and moving on to a new device to plot the next 4 and so on. (I want
to do this in R and not export to a pdf etc)

I notice that in S-PLUS multiple tabs are opened in one device, R does
not seem to have this capability and as I plot the next 4 graphs they
overwrite the previous 4.

Well, on Windows there is a history mechanism that has the same effect as tabs. You haven't told us your OS (nor the screen device).


I imagine a 'for' loop could solve this by opening a new active device
at the end of the loop, but I feel this is inefficient and that there
must be a solution by modifying the lattice object.

Let z be a lattice object. (histogram for example)

Let the layout be.

layout=cbind(c(1,2),c(3,4))

    [,1] [,2]

[1,]    1    3

[2,]    2    4

Print(z)

Thus giving 4 graphs per page on multiple pages until the lattice object
has been completely plotted.

I hope this is clear

Thanks all

Oli
