element_roundrect
The element_roundrect
works like
element_rect
to draw round rectangle background. We can use
it to adjust theme elements, including legend, strip, panel and plot
background.
p <- ggplot(mpg, aes(displ, cty)) + geom_point()
p <- p + facet_grid(cols = vars(cyl))
p <- p + theme(strip.background=element_roundrect(fill="grey40", color=NA, r=0.15))
p
p2 <- ggplot(mtcars, aes(mpg, disp, color=factor(cyl), size=cyl)) +
geom_point()
p2 + theme(legend.background=element_roundrect(color="#808080", linetype=2))
gglegend
p <- ggplot(mtcars, aes(mpg, disp)) + geom_point()
data <- data.frame(colour = c("red", "blue"), VALUE = c("A", "B"))
gglegend(aes(colour = VALUE, label=VALUE), data, geom_text, p)
set_font
d <- data.frame(x=rnorm(10), y=rnorm(10), lab=LETTERS[1:10])
p <- ggplot(d, aes(x, y)) + geom_text(aes(label=lab), size=5)
set_font(p, family="Times", fontface="italic", color='firebrick')
facet_set
Manually specifying facet labels.
library(ggplot2)
library(ggfun)
p <- ggplot(mtcars, aes(disp, drat)) +
geom_point() +
facet_grid(cols=vars(am), rows=vars(cyl))
p + facet_set(label=c(`0`="Zero", `6`="Six"))
Supports labeller:
p + facet_set(label=label_both)
Add a facet label to a plot.
p + facet_set(label="TEST")
With the ggplotify
package, we can use facet_set
to add a facet label to
almost any plot in R.
## please try:
ggplotify::as.ggplot(~barplot(1:10, col=rainbow(10))) +
facet_set('a barplot in base')
