themes_*() scale relevant elements with argument base_size.

[strengejacke]

This allows us to scale a plot and ensure that proportions of all relevant plot-elements (mostly titles/texts) are automatically scaled properly.

Example:

library(ggplot2)
library(see)

data(iris)
iris$group4 <- as.factor(sample(1:4, size = nrow(iris), replace = TRUE))
iris$group5 <- as.factor(sample(1:5, size = nrow(iris), replace = TRUE))

d1 <- data.frame(
  x = rep(1:20, 3),
  y = c(
    seq(2, 4, length.out = 20),
    seq(3, 6, length.out = 20),
    seq(5, 3, length.out = 20)
  ),
  group = rep(factor(1:3), each = 20)
)

ggplot(d1, aes(x, y, colour = group)) +
  geom_line(linewidth = 1) +
  scale_color_social() +
  theme_lucid()

ggplot(d1, aes(x, y, colour = group)) +
  geom_line(linewidth = 1) +
  scale_color_social() +
  theme_lucid(base_size = 25)

This is useful if you want to scale plot in RStudio / Positron, to copy it into clipboard and paste it into some office documents, and have proper proportions / scaling of plot elements.
