本文介绍了使用包裹在函数中的ggplot2中的重新排序的处理方法,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 我正在构建一个函数来包装一些ggplot2,如下所示: df clevelandPlot< - function(dataFrame,xValue,yValue){ ggplot(data = dataFrame,aes_string(x = xValue,y = yValue))+ geom_segment(aes_string(yend = yValue),xend = 0,color =grey50)+ geom_point(size = 3)+ scale_x_continuous(expand = c(0.01,0))+ theme_bw()+ theme(panel.grid.major.y = element_blank())+ xlab(重要性)+ ylab() } 此功能有效: clevelandPlot(df,Overall_Imp,Variable) 但是,当我尝试使用以下代码对值进行重新排序时,它不起作用: clevelandPlot< - function(dataFrame,xValue,yValue){ ggplot(data = dataFrame,aes_string(x = xValue,y = reorder (yValue,xValue)))+ geom_segment(aes_string(yend = yValue),xend = 0,color =grey50)+ geom_point(size = 3)+ scale_x_continuous(expand = c(0.01,0))+ theme_bw()+ theme(panel.grid.major.y = element_blank())+ xlab(重要性)+ ylab() } strong> 如何在y轴上按照递减顺序重新排列变量(图表顶部的最大值)? 解决方案 clevelandPlot< - function(dataFrame,xValue,yValue){ ix< - sort.int(dataFrame [,xValue],递减= FALSE,index.return = TRUE)$ ix dataFrame [,y Value]< - factor(dataFrame [,yValue],dataFrame [ix,yValue]) ggplot(data = dataFrame,aes_string(x = xValue,y = yValue))+ geom_segment(aes_string(yend = yValue),xend = 0,color =grey50)+ geom_point(size = 3)+ scale_x_continuous(expand = c(0.01,0))+ theme_bw()+ theme(panel.grid.major.y = element_blank())+ xlab(重要性)+ ylab()} clevelandPlot(df,Overall_Imp,Variable) BackgroundI am building a function to wrap some ggplot2 as follow:df <- data.frame("Variable" = c("CHK_ACCOUNT3", "AMOUNT", "DURATION"), "Overall_Imp" = c(71.44, 54.24, 34.84)) clevelandPlot <- function (dataFrame, xValue, yValue) { ggplot(data = dataFrame, aes_string(x=xValue, y=yValue)) + geom_segment(aes_string(yend = yValue), xend = 0, colour = "grey50") + geom_point(size=3) + scale_x_continuous(expand = c(0.01, 0)) + theme_bw() + theme(panel.grid.major.y = element_blank()) + xlab("Importance") + ylab("")}This function works:clevelandPlot(df, "Overall_Imp", "Variable")But when I try to reorder the values with the following code, it does not work:clevelandPlot <- function (dataFrame, xValue, yValue) { ggplot(data = dataFrame, aes_string(x=xValue, y=reorder(yValue, xValue))) + geom_segment(aes_string(yend = yValue), xend = 0, colour = "grey50") + geom_point(size=3) + scale_x_continuous(expand = c(0.01, 0)) + theme_bw() + theme(panel.grid.major.y = element_blank()) + xlab("Importance") + ylab("")}QuestionHow to reorder the variable in the y axis in a decreasing order (biggest value at the top of the plot)? 解决方案 clevelandPlot <- function (dataFrame, xValue, yValue) { ix <- sort.int(dataFrame[,xValue], decreasing = FALSE, index.return = TRUE)$ix dataFrame[,yValue] <- factor(dataFrame[,yValue], dataFrame[ix,yValue]) ggplot(data = dataFrame, aes_string(x=xValue, y=yValue)) + geom_segment(aes_string(yend = yValue), xend = 0, colour = "grey50") + geom_point(size=3) + scale_x_continuous(expand = c(0.01, 0)) + theme_bw() + theme(panel.grid.major.y = element_blank()) + xlab("Importance") + ylab("")}clevelandPlot(df, "Overall_Imp", "Variable") 这篇关于使用包裹在函数中的ggplot2中的重新排序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!
