我有一个包含四列AGE,DIASTOLIC,BMI,EVER.PREGNANT的csv文件。我希望绘制直方图,比较x轴的AGE和y轴的DIASTOLIC。我怎么能这样做?我写的代码是:

Sheet=read.csv("/home/prajnan/Downloads/1739230_1284354330_PIMA.csv - 1739230_1284354330_PIMA.csv.csv",sep=",", header = T) hist(Sheet[2],Sheet[3]$AGE$DIASTOLIC)

我得到的错误是:

Error in hist.default(Sheet[2], Sheet[3]$AGE$DIASTOLIC) :'x' must be numeric 哪里出错了?先谢谢。

注意:dput(head(Sheet,10))的输出是:

首先,直方图是显示单个分布中的值的频率的图。您无法使用它来比较两个值。要查看数据集中的单个分布,您可以执行以下操作:

        .state('userInfo', {
            url: '/userInfo',
            parent: 'menu',
            params: {
                id: null,
                name: null,
                email: null,
                password: null
            },
            templateUrl: 'app/components/userInfo/userInfo.view.html',
            controller: 'userInfoCtrl',
            data: {}
        })

        .state('register', {
            url: '/register',
            params: {
                email: null
            },
            templateUrl: 'app/components/userInfo/userInfo.view.html',
            controller: 'userInfoCtrl',
            data: {}
        })

同样地:

hist(sheet$AGE)

如果您希望将它们一起绘制以比较两个分布,则可以执行此操作:

hist(sheet$DIASTOLIC)

但是,如果您想直接比较两个变量,则直方图可能不是您想要的。你可以从这样一个简单的散点图开始:

par(mfrow = c(2, 1))
hist(sheet$AGE)
hist(sheet$DIASTOLIC)
