1.制造一些图
制造一些图片,为后续的操作做准备
library(ggplot2)# This example uses the ChickWeight dataset, which comes with ggplot2# First plotp1 <- ggplot(ChickWeight, aes(x=Time, y=weight, colour=Diet, group=Chick)) + geom_line() + ggtitle("Growth curve for individual chicks")# Second plotp2 <- ggplot(ChickWeight, aes(x=Time, y=weight, colour=Diet)) + geom_point(alpha=.3) + geom_smooth(alpha=.2, size=1) + ggtitle("Fitted growth curve per diet")# Third plotp3 <- ggplot(subset(ChickWeight, Time==21), aes(x=weight, colour=Diet)) + geom_density() + ggtitle("Final weight, by diet")# Fourth plotp4 <- ggplot(subset(ChickWeight, Time==21), aes(x=weight, fill=Diet)) + geom_histogram(colour="black", binwidth=50) + facet_grid(Diet ~ .) + ggtitle("Final weight, by diet") + theme(legend.position="none") # No legend (redundant in this graph)
图片列表
使用ggarrange函数进行合并,可指定列和行
library(ggpubr) plist <- list(p1, p2, p3, p4)do.call("ggarrange", c(plist, ncol=2, nrow=2))
使用一些其他的也可以例如cowplot的函数和grid.arrange函数,但是我更加喜欢ggarrange.
