Plotting plotSmooth objects on a grid

Source: R/gridPrint.R

This is a wrapper for gridExtra::grid.arrange, which allows to plot several plotSmooth objects on a grid.

gridPrint(...)

Arguments

...

arguments to be passed to gridExtra::grid.arrange.

Details

This function simply extracts the ggplot objects contained in any object of class plotSmooth and passes them to gridExtra::grid.arrange.

Examples

library(mgcViz)
n  <- 1e3
x1 <- rnorm(n)
x2 <- rnorm(n)
dat <- data.frame("x1" = x1, "x2" = x2,
                  "y" = sin(x1) + 0.5 * x2^2 + pmax(x2, 0.2) * rnorm(n))
b <- bam(y ~ s(x1)+s(x2), data = dat, method = "fREML", discrete = TRUE)
b <- getViz(b)

o1 <- plot( sm(b, 1) ) + l_fitLine() + l_ciLine()
o2 <- plot( sm(b, 2) ) + l_fitLine() + l_ciLine()
qpl <- qq(b)

# All on one page, method 1:
gridPrint(o1, o2, qpl, ncol = 2)

# All on one page, method 2:
gridPrint(grobs = list(o1, o2, qpl), ncol = 2)

# Works also when some ggplot objects are present
gridPrint(o1, o2, qpl, ggplot(), ncol = 2)
