R语言 ggplot 字体大小

在R语言中，可以使用ggplot2包来设置图形的字体大小。首先，如果要在单个图片中设置字体大小，可以使用theme_grey函数来设置基本字体大小，例如theme_grey(base_size = 18)，然后使用qplot或ggplot函数创建图形，如qplot(1:10, 1:10)或ggplot(mtcars, aes(x = mpg, y = cyl)) geom_point()。同样地，如果要全局设置字体大小，可以使用theme_set函数，例如theme_set(theme_gray(base_size = 18))，然后再创建图形。可以根据需要调整字体大小的数值，例如base_size = 18或base_size = 50。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
