Hello,
Here are two ways.
The first is an adaptation from your code. It uses facet_wrap_paginate,
not *_grid_*.
plotObj2 <- vector("list",2)
for(pg in 1:2) {
plotObj2[[pg]] <- ggplot(egDat) +
geom_point(aes(y = obsd, x = x),
na.rm = TRUE, shape = 20, colour = "blue") +
geom_line(aes(y = fit2, x = cPred)) +
facet_wrap_paginate(facets = ~Trt,
ncol = 4, nrow = 3, page = pg) +
theme_bw()
}
print(plotObj2)
The second is an adaptation of SO[1]. It needs two calls to the plot
code and it's slower but gets the job done.
g <- ggplot(egDat) +
geom_point(aes(y = obsd, x = x),
na.rm = TRUE, shape = 20, colour = "blue") +
geom_line(aes(y = fit2, x = cPred)) +
facet_wrap_paginate(facets = ~Trt, ncol = 4, nrow = 3, page = 1) +
theme_bw()
n <- n_pages(g)
for(i in 1:n){
print(g + facet_wrap_paginate(~Trt, ncol = 4, nrow = 3, page = i))
}
print(g)
Hope this helps,
Rui Barradas

I am trying to produce a ggplot2 graphic in which there is a single
conditioning variable with a large number of levels (24).
If I use facet_grid() I get a plot with either 24 rows or 24 columns,
both of which look like hell.
I thought that facet_grid_paginate() would rescue me, but it doesn't
seem to. I ask for 3 rows and 4 columns, and thought that I would get
two 3 x 4 pages Instead I get six pages with only one row (of four
facets) per page.
Am I misunderstanding something? Doing something silly? Or is this a bug?
I have attached a reproducible example, along with the data set on which
it depends.
Grateful for any insight.
cheers,
Rolf Turner
