在 R 中组合图 [英] Combine plots in R

问题描述

我有几个图想将它们组合在一起并为组合图添加标题，但不知何故我无法使用 R 组合它们.(使用 RStudio)

I have several plots that I want to combine them together and add a title to the combined plot, but somehow I cannot combine them using R. (using RStudio)

1. 组合使用 plot(resid(lme)) 绘制的两个残差图，其中 lme 是线性混合模型.
2. 合并使用 interaction.plot(x1,x2,y) 绘制的两个交互图，其中 x1 和 x2 是两个自变量，y 是因变量.

1. Combine two residual plots plotted by using plot(resid(lme)) where lme is a linear mixed model.
2. Combine two interaction plots plotted by using interaction.plot(x1,x2,y) where x1 and x2 are the two independent variables, and y is the dependent variable.

我尝试将绘图存储为变量并使用 grid.arrange，但它们无法存储到变量中(仅在绘图区域生成绘图).

I tried to store the plots as variables and use grid.arrange, but they cannot be stored into a variable (just produce the plot in the plot area).

即

> int1 <- interaction.plot(data_pos_10$Day,data_pos_10$Drug,data_pos_10$Tumor.Volume,
+                  xlab="Day",ylab="Tumor Volume",main="Interaction Plot Batch 10",
+                  legend=F,
+                  col=c("red","red","green","black","blue"),
+                  lwd=2,
+                  lty=c(1,2,3,4,5))
> int1
NULL

推荐答案

在绘制代码之前，运行 par(mcol=c(2,1)) 以垂直堆叠它们或 par(mcol=c(1,2)) 水平堆叠它们.

Before you do your plotting code, run par(mcol=c(2,1)) to stack them vertically or par(mcol=c(1,2)) to stack them horizontally.
