What in the world is so horrible about for loops?

How about


lattice.plots <- list(xyplot(rnorm(10) ~ 1:10, type = "b"),
                                     xyplot(rnorm(10) ~ 1:10, type = "b"),
                                     xyplot(rnorm(10) ~ 1:10, type = "b"),
                                    xyplot(rnorm(10) ~ 1:10, type = "b"))

do.call(grid.arrange, lattice.plots)

There is most likely a loop hidden somewhere in the do.call function ;-)

Subject: [R] plot a list of trellis objects

Dear Rxperts

Is there a way to control the display order (or simplistically control
panel layout) of a list of trellis objects without using a for loop (or
whatever)?

I just realize that gridExtra has that feature.. (grid.arrange)...

But, converting each of those elements of the list of trellis objects into
an argument to grid.arrange seems to negate the simplicity.. In addition,
if I were to use grid.arrange on a list of trellis objects, is there a way
to pass the list elements as arguments to grid.arrange?

If you have other suggestions, please do..

Regards,
Santosh

Well to be in control:

Please read carefully the help to grid.layout

Create a Grid Layout

Description:

     This function returns a Grid layout, which describes a subdivision
     of a rectangular region.

Usage:

     grid.layout(nrow = 1, ncol = 1,
             widths = unit(rep(1, ncol), "null"),
             heights = unit(rep(1, nrow), "null"),
             default.units = "null", respect = FALSE,
             just="centre")

to control your settings more carefully.     

Please read the help to lattice::print

C_05_print.trellis           package:lattice           R Documentation

Plot and Summarize Trellis Objects

Description:

     The 'print' and 'plot' methods produce a graph from a '"trellis"'
     object.  The 'print' method is necessary for automatic plotting.
     'plot' method is essentially an alias, provided for convenience.
     The 'summary' method gives a textual summary of the object.  'dim'
     and 'dimnames' describe the cross-tabulation induced by
     conditioning.  'panel.error' is the default handler used when an
     error occurs while executing the panel function.

Usage:

     ## S3 method for class 'trellis'
     plot(x, position, split,
          more = FALSE, newpage = TRUE,
          packet.panel = packet.panel.default, 
          draw.in = NULL,
          panel.height = lattice.getOption("layout.heights")$panel,
          panel.width = lattice.getOption("layout.widths")$panel,
          save.object = lattice.getOption("save.object"),
          panel.error = lattice.getOption("panel.error"),
          prefix,
          ...)


To be in superior control.

Happy plotting.




Yours sincerely / Med venlig hilsen

Hi

for print.trellis you could make a function and supply the plots as
arguments ?list and then print them
There are various ways of doing it and you could have a matrix as an
argument with the proportions and access them

Duncan

Subject: Re: [R] plot a list of trellis objects

I forgot to add.. printltrellis seems to take in only one trellis object at
a time.. so.. I think I would need to use a loop for varying the column/row
indices, etc...

Is that the only way (other than grid.arrange)? Is column/row/page control
possible through grid.arrange..?
