Dear Tom,
You can control the size of the axis title in ggplot2. It is described in the
ggplot2 book. Have a look at Chapter 8: Polishing your plots for publication.
You can find the book on the ggplot2 website.
I tend to create my own theme for some specific type of plots. Below you can
find a theme for plots with rotated labels on the X-axis. Using such a theme is
similar to adding an extra geom.
ggplot(dat, aes(x = factor(time), y = volume)) + geom_boxplot() +
geom_jitter(aes(colour = id)) + labs(x = "time", y = volume) + BaseThemeX90()
BaseThemeX90 <- function(base_size = 10) {
structure(list(
axis.line = theme_blank(),
axis.text.x = theme_text(size =
base_size * 0.8 , lineheight = 0.9, colour = "grey50", hjust = 1, angle = 90),
axis.text.y = theme_text(size =
base_size * 0.8, lineheight = 0.9, colour = "grey50", hjust = 1),
axis.ticks =
theme_segment(colour = "grey50"),
axis.title.x = theme_text(size =
base_size),
axis.title.y = theme_text(size =
base_size, angle = 90),
axis.ticks.length = unit(0.15, "cm"),
axis.ticks.margin = unit(0.1, "cm"),
legend.background =
theme_rect(colour=NA),
legend.key =theme_rect(fill =
"grey95", colour = "white"),
legend.key.size = unit(1.2, "lines"),
legend.text = theme_text(size =
base_size * 0.7),
legend.title = theme_text(size =
base_size * 0.8, face = "bold", hjust = 0),
legend.position = "right",
panel.background = theme_rect(fill =
"grey90", colour = NA),
panel.border = theme_blank(),
panel.grid.major = theme_line(colour =
"white"),
panel.grid.minor = theme_line(colour =
"grey95", size = 0.25),
panel.margin = unit(0.25, "lines"),
strip.background = theme_rect(fill =
"grey80", colour = NA),
strip.label = function(variable,
value) value,
strip.text.x = theme_text(size =
base_size * 0.8),
strip.text.y = theme_text(size =
base_size * 0.8, angle = -90),
plot.background = theme_rect(colour =
NA),
plot.title =theme_text(size =
base_size * 1.2),
plot.margin = unit(c(1, 1, 0.5,
0.5), "lines")
), class = "options")
}

To call in the statistician after the experiment is done may be no more than
asking him to perform a post-mortem examination: he may be able to say what the
experiment died of.

Onderwerp: [R] is there any option like cex.axis in ggplot2?
Dear list,
I made boxplots using ggplot and want to control for x- and yaxis. Using "plot"
I can do it by setting cex.axis equally to any size but can't figure out how to
do it with ggplot.
ggplot(dat, aes(x = factor(time), y = volume)) +
opts(axis.title.x=theme_text(size=8),axis.title.y=theme_text(size=8)) +
geom_boxplot() + geom_jitter(aes(colour
