Yes of course (why didn't you yourself read the man/help pages? That's the way I learned R).

If you see the help to grid.arrange:

arrangeGrob             package:gridExtra              R Documentation

arrangeGrob

Description:

     arrange ggplot2, lattice, and grobs on a page

Usage:

       arrangeGrob(..., as.table = FALSE, clip = TRUE,
         main = NULL, sub = NULL, left = NULL, legend = NULL)

Arguments:

     ...: plots of class ggplot2, trellis, or grobs, and valid
          arguments to grid.layout


For the ellipses:

The arguments to to grid.layout is your savior:

(here is the help to grid.layout):


grid.layout                package:grid                R Documentation

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")

Arguments:

    nrow: An integer describing the number of rows in the layout.


And then for the call to do.call

do.call                  package:base                  R Documentation

Execute a Function Call

Description:

     'do.call' constructs and executes a function call from a name or a
     function and a list of arguments to be passed to it.

Usage:

     do.call(what, args, quote = FALSE, envir = parent.frame())

Arguments:

    what: either a function or a non-empty character string naming the
          function to be called.

    args: a _list_ of arguments to the function call.  The 'names'
          attribute of 'args' gives the argument names.


The args argument saves you:

This suggests me to do:


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, list(lattice.plots, ncol = 1))

That does NOT WORK, damn someone, even though the help to do.call says that args should be a _list_ (damn you isn't that a LIST)

However this works:

do.call(grid.arrange,c(lattice.plots, ncol = 1))


WHAT IS THE DIFFERNCE BETWEEN c() and list()????????????????

Have a nice day to all of you.

And thank you all developers for R. I cannot live without it.

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

Thanks for the suggestion..
Is there a way I can include arguments to the grid.arrange function?

I tried in your example something like...
gridar <- function(x,ncol=2,...) grid.arrange(x,...)
do.call(gridar, lattice.plots);

I could not make it work when I try to control number of columns/rows and have multiple pages the way possible using print.trellis

Regards,
Santosh

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 ;-)
