本文介绍了如何将多个ggplot2对象以相同的比例组合起来的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 假设我有以下数据: pre $ lt; code> mymatrix1 mymatrix2 mymatrix3 mymatrix1 [,1]< - sample(0:1,105,replace = TRUE) mymatrix1 [,2]< - rorm(105,52,2) mymatrix2 [ ,1] mymatrix2 [,2] mymatrix3 [,1]<示例(0:1,112,replace = TRUE) mymatrix3 [,2]< - rnorm(112,70,2) for(i in 1:3){colnames (mydata [[i]]) mydata< - list(mymatrix1,mymatrix2,mymatrix3) $ b我得到mydata [[1]]的图表,因为我需要它使用以下内容: qplot(class,readcount,data = as.data.frame(mydata [[1]]),geom =boxplot,fill = factor(class))+ geom_jitter(position = position_jitter(w = 0.1,h = 0.1))+ scale_x_continuous(中断= c(0,1),labels = c(0,1)) 现在,我将如何获得彼此相邻的所有箱形图(如此遍历列表)?使用grid.arrange?但是,这会给我不同的规模......如果我想要相同的规模呢?有人可以同时显示吗?解决方案查看 facet_wrap 。 library(ggplot2) mymatrix1 mymatrix2 mymatrix3 $ b $ mymatrix1 [,1] mymatrix1 [,2] mymatrix2 [ 1] mymatrix2 [,2] mymatrix3 [,1]< - sample (0,1,112,replace = TRUE) mymatrix3 [,2] mydata (i在1:3){ mydata [[i]] colnames(mydata [ [i]])< - c(class,readcount,group)} mydata< - as.data.frame(do .call(rbind,mydata)) ##固定比例p geom_jitter(position = position_jitter(w = 0.1,h = 0.1))+ scale_x_continuous(breaks = c(0,1) ,标签= c(0,1))+ facet_wrap(〜group) ## free scales p + facet_wrap(〜group, scale =free) Suppose I have the following data:mymatrix1 <- matrix(data = 0, nrow = 105, ncol =2)mymatrix2 <- matrix(data = 0, nrow = 108, ncol =2)mymatrix3 <- matrix(data = 0, nrow = 112, ncol =2)mymatrix1[,1] <- sample(0:1, 105, replace= TRUE)mymatrix1[,2] <- rnorm(105, 52, 2)mymatrix2[,1] <- sample(0:1, 108, replace= TRUE)mymatrix2[,2] <- rnorm(108, 60, 2)mymatrix3[,1] <- sample(0:1, 112, replace= TRUE)mymatrix3[,2] <- rnorm(112, 70, 2)for(i in 1:3){ colnames(mydata[[i]]) <- c("class", "readcount") }mydata <- list(mymatrix1, mymatrix2,mymatrix3)I get the plot for mydata[[1]] as I want it using the following:qplot(class, readcount, data = as.data.frame(mydata[[1]]), geom="boxplot", fill = factor(class))+ geom_jitter(position=position_jitter(w=0.1,h=0.1))+ scale_x_continuous(breaks=c(0,1), labels=c("0", "1"))Now, how would I get all the box plots next to each other (so iterate over the list)? Using grid.arrange? But that would give me different scales... what if I wanted the same scale? Can someone show both? 解决方案 Check out facet_wrap.library(ggplot2)mymatrix1 <- matrix(data = 0, nrow = 105, ncol =2)mymatrix2 <- matrix(data = 0, nrow = 108, ncol =2)mymatrix3 <- matrix(data = 0, nrow = 112, ncol =2)mymatrix1[,1] <- sample(0:1, 105, replace= TRUE)mymatrix1[,2] <- rnorm(105, 52, 2)mymatrix2[,1] <- sample(0:1, 108, replace= TRUE)mymatrix2[,2] <- rnorm(108, 60, 2)mymatrix3[,1] <- sample(0:1, 112, replace= TRUE)mymatrix3[,2] <- rnorm(112, 70, 2)mydata <- list(mymatrix1, mymatrix2,mymatrix3)for(i in 1:3){ mydata[[i]] <- cbind(mydata[[i]], i) colnames(mydata[[i]]) <- c("class", "readcount", "group")}mydata <- as.data.frame(do.call(rbind, mydata))## fixed scalesp <- qplot(class, readcount, data = mydata, geom="boxplot", fill = factor(class)) + geom_jitter(position=position_jitter(w=0.1,h=0.1)) + scale_x_continuous(breaks=c(0,1), labels=c("0", "1")) + facet_wrap(~ group)## free scalesp + facet_wrap(~ group, scales = "free") 这篇关于如何将多个ggplot2对象以相同的比例组合起来的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 10-23 02:17
