本文介绍了如何使用ggplot()手动将颜色设置为分类变量?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 这是我的示例数据 table1 xaxis yaxis ae work 1 5 35736 Attending_Education Working 2 6 72286上岗教育工作 3 7 133316上岗教育工作 4 8 252520上岗教育工作 5 9 228964上岗教育工作 6 10 504676上岗教育工作 这是我使用的代码。 p< -ggplot(table1,aes(x = table1 $ xaxis,y = table1 $ yaxis)) Economic_Activity<-系数(表1 $工作) Education_Status<-系数(表1 $ ae) p< -p + geom_point(aes(color = Education_Status,shape = Economic_Activity ),size = 4) p + xlab(人口年龄)+ ylab(参加教育机构的人数)+ ggtitle(按经济活动状况参加教育的机构::印度2001) 这是我得到的输出。 I希望在此图中做两件事。 我希望为此分类变量手动设置颜色(Attending_Education\Not_AE) 。例如。 Attending_Education为深绿色,Not_AE为红色。 在经济活动的传说中,我不需要黑色作为工作类别,而不是黑色。我需要深绿色和红色。 是R的新手。我也尝试过palette()@下面的链接。但似乎没有任何效果 如何将特定颜色分配给R中的特定类别变量? 注意:请查看我的要求。 类别Attending_Education Not_AE工作的绿色\圆形红色Red圆形Not_Working的绿色\三角形形状红色\三角形 我们非常感谢您的帮助。谢谢大家。解决方案第一个问题,您需要使用 scale_colour_manual : p + xlab(人口年龄)+ ylab(参加教育机构数量)+ ggtitle(按经济活动状况参加教育的机构::印度2001)+ scale_colour_manual(values = c( Attending_Education =深绿色, Not_AE =红色)) 第二秒钟,我不清楚您想要什么。经济活动以形状而非颜色来表示。那么在该图例中显示深绿色/红色是什么意思? This is my sample data table1 xaxis yaxis ae work1 5 35736 Attending_Education Working2 6 72286 Attending_Education Working3 7 133316 Attending_Education Working4 8 252520 Attending_Education Working5 9 228964 Attending_Education Working6 10 504676 Attending_Education WorkingThis is the code i had used. p<-ggplot(table1,aes(x=table1$xaxis,y=table1$yaxis))Economic_Activity<-factor(table1$work)Education_Status<-factor(table1$ae)p<-p+geom_point(aes(colour=Education_Status,shape=Economic_Activity),size=4)p+xlab("Population Ages")+ylab("Attending Education Institutions Count")+ggtitle("Attending Educational Institutions by Economic Activity Status :: INDIA 2001")This is the output i got.I Wish to do two things in this graph.i wish to set color manually to this categorical variables (Attending_Education\Not_AE). For example. Dark Green color for Attending_Education and red color for Not_AE.In the legend of economic activity, i don't need black color for working\not_working category. i need the Dark green and red color.iam new to R. i had tried palette() too found @ below link. but nothing seems to workHow to assign specfic colours to specifc categorical variables in R?Note: please look at my requirements. Categories Attending_EducationNot_AEWorkingGreen color\Round ShapeRed Color\Round shapeNot_WorkingGreen color\Triangle ShapeRed Color\Triangle shapeYour help is appreciated. Thanking u all. 解决方案 For your first question, you need to use scale_colour_manual:p + xlab("Population Ages") + ylab("Attending Education Institutions Count") + ggtitle("Attending Educational Institutions by Economic Activity Status :: INDIA 2001") + scale_colour_manual(values = c("Attending_Education" = "dark green", "Not_AE" = "red"))For your second, I'm not clear what you want. Economic activity is represented as shape, not colour. So what would be the meaning of having dark green/red colours within that legend? 这篇关于如何使用ggplot()手动将颜色设置为分类变量?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! 09-17 06:02
