[R] Changing layout in grid.arrange

[Roy Mendelssohn - NOAA Federal]

Thanks, it took some digging in the internet, but I figured out how to do it.

The first thing is how to pass options to grid.arrange when used in do.call.  It takes a list, which I tried in several different ways,  the list has to be of a certain form, so something like:

> args.list <- c(plots,list(nrow=5,ncol=2))
> do.call(grid.arrange,args.list)


The second thing is to interleave sequences before doing the lapply, as in:

x<- 1:5
y<-6:10
iOrder<-c(rbind(x,y))

I should add that Dennis Murphy sent this solution off-line, I will add it for completeness:

> require(ggplot2)
> plots = lapply(1:10, function(.x) qplot(1:10,rnorm(10), main=paste("plot",.x)))
> require(gridExtra)
> do.call(grid.arrange, c(plots[as.vector(gdata::interleave(1:5, 6:10))],
>                         list(nrow = 5)))


Either of these produces a grid of plots with 5 rows and two columns, which is what I was after.

What I would like instead is for the layout to have 2 columns and 5 rows, with graphs 1-5 going down the first column, graphs 6-10 going down the second column but almost everything I have tried has failed.  Any help appreciated.
