如何用r语言绘制多变量散点图,第1张

给你一些代码，你慢慢研究：install.packages('ggplot2')library(ggplot2)ggplot(a)+geom_bar(aes(x1,y,fill/col=x1/x2),position='dodge',stat='summary',fun='sum'/'mean')条形图+theme(text = element_text(family='Kai'))ggplot(a)+geom_boxplot(aes(x1,y,col=x1/x2))箱线图ggplot(a)+geom_point(aes(x1,y,col=x1/x2),position=position_jitter(width=0.04))散点图1+geom_point(aes(x1,y,col=x1/x2),stat='summary',fun='sum'/'mean')+散点2+geom_line(aes(x1,y,group=1/x2,col=x1/x2),stat='summary',fun='sum'/'mean')+折线3+geom_errorbar(aes(x=x1,ymin=y-se,ymax=y+se,col=x1/x2),position=position_dodge(0.9),width=0.2)+误差棒4+geom_text(aes(x1,y,label=marker,col=x1/x2),position=position_dodge(0.9)vjust=2或y+2)+显著字母ggplot(a,aes(x1,y,fill/col=x1/x2))+geom_bar(position='dodge',stat='summary',fun='sum'/'mean')+geom_errorbar(aes(ymin=y-se,ymax=y+se),position=position_dodge(0.9),width=0.2)+geom_text(aes(label=marker),position=position_dodge(0.9),vjust=-2)条形图+误差棒+显著字母（坐标写一次即可）ggplot(a,aes(x1,y,col=x1/x2))+geom_point(position=position_jitter(width=0.04),stat='summary',fun='sum'/'mean')+geom_line(aes(group=1/x2),stat='summary',fun='sum'/'mean')+geom_errorbar(aes(ymin=y-se,ymax=y+se),position=position_dodge(0.9),width=0.2)+geom_text(aes(label=marker),position=position_dodge(0.9),vjust=-2)散点图+折线+误差棒+显著字母（坐标写一次即可）+geom_density(aes(y=liqi))密度图(1个数值型)+geom_area(aes(x=tan,y=liqi))区域图(2个数值型)+geom_smooth(aes(x=tan,y=liqi,group/col=chong),formula=y~x,method='lm',se=F)拟合图，分组/线条颜色(2个数值型)+facet_wrap(~riqi,ncol/nrow=2,labeller='label_both/value')分面图，每行或每列分面数，分面标题+xlab('自变量1（单位）')+ylab('因变量（单位）')+scale_fill_discrete(name='自变量2')更改轴和图例名称+coord_cartesian(ylim= c(0,80))限定轴范围(fill=x1/x2,有此即可变色)+scale_fill_manual(values = c('grey70', 'grey50', 'grey30'))改变条形填充颜色(颜色数量=分组数量)(col=x1/x2,有此即可变色)+scale_color_manual(values = c('red', 'orange', 'yellow'))改变颜色（颜色数量=分组数量）

require(ggplot2)

vd = rbind(data.frame(v=vd1, y=y, t=as.factor(1)), data.frame(v=vd2, y=y, t=as.factor(0)))

ggplot(vd, aes(x=v, y=y)) + geom_point(aes(color=t))
