ggsave_mpinl_poster_portrait: Saving helper functions

In joerodd/mpinltheme: ggplot2 Theme Consistent with MPI for Psycholinguistics Corporate Identity

Description

These functions are wrappers around the ggplot2 convenience function ggsave, for saving a plot. They default to saving the last plot that you displayed. The width is in each case predefined to have the correct width for the MPI poster templates. Do adjust the height though! There are versions for portrait and landscape poster templates, since these have different column widths.

Usage

plot + theme_mpinl_poster()
ggsave_mpinl_poster_portrait("posterfigure_1.pdf") # The default height is
ggsave_mpinl_poster_portrait("posterfigure_2.pdf",height = 200, units = "mm")
ggsave_mpinl_poster_landscape("outputfilename_landscape.pdf")

ggsave_mpinl_poster_landscape(filename, plot = ggplot2::last_plot(),
  device = NULL, path = NULL, scale = 1, width = NA, height = NA,
  units = c("in", "cm", "mm"), dpi = 500, limitsize = TRUE, ...)

Arguments

filename	File name to create on disk.
plot	Plot to save, defaults to last plot displayed.
device	Device to use. Can be either be a device function (e.g. png()), or one of "eps", "ps", "tex" (pictex), "pdf", "jpeg", "tiff", "png", "bmp", "svg" or "wmf" (windows only).
path	Path to save plot to (combined with filename).
scale	Multiplicative scaling factor.
width	Plot size in units ("in", "cm", or "mm"). If not supplied, uses the size of current graphics device.
height	Plot size in units ("in", "cm", or "mm"). If not supplied, uses the size of current graphics device.
units	Plot size in units ("in", "cm", or "mm"). If not supplied, uses the size of current graphics device.
dpi	Plot resolution. Also accepts a string input: "retina" (320), "print" (300), or "screen" (72). Applies only to raster output types.
limitsize	When TRUE (the default), ggsave will not save images larger than 50x50 inches, to prevent the common error of specifying dimensions in pixels.
...	Other arguments passed on to the graphics device function, as specified by device.

Examples

mtcars2 <- within(mtcars, {
vs <- factor(vs, labels = c("V-shaped", "Straight"))
am <- factor(am, labels = c("Automatic", "Manual"))
cyl  <- factor(cyl)
gear <- factor(gear)
})

library(ggplot2)
library(mpinltheme)

p1 <- ggplot(mtcars2) +
  geom_point(aes(x = wt, y = mpg, colour = gear)) +
    labs(title = "Fuel economy declines as weight increases",
         subtitle = "(1973-74)",
         x = "Weight (1000 lbs)",
         y = "Fuel economy (mpg)",
         colour = "Gears")

p1 + scale_colour_discrete_mpinl() + theme_mpinl_poster()
ggsave_mpinl_poster_portrait("outputfilename.pdf")
