0引言

相比于基础包中的画图思路和风格，ggplot2在R语言中被很多使用者广泛应用。本文介绍一个基于ggplot2开发的包ggsci。这个包里有一些期刊的配色风格，可以直接通过**+**使用。下面是具体的介绍

1、安装

install.packages("ggsci")

2、载入

library("ggsci")

3、主要函数

> ls("package:ggsci")

4、实例（配色）

4.1基本图

library('patchwork')
p1 <- ggplot(iris, aes(Sepal.Length, Sepal.Width, colour = Species)) +
  geom_point(alpha = 0.4, position = "jitter") +
  geom_smooth(method = "loess", span = 0.9, se = FALSE, alpha = 0.05)

4.2 加主题

  p2 <- p1 + theme_bw() +
  theme(legend.position = "top")

4.3 改配色

p3 <- p2 + scale_colour_jama() + scale_fill_jama()

4.4 展示

p1 + p2 + p3
