我正在尝试vuetify在我的项目中实施。我想分开 <v-navigation-drawer>，</v-toolbar>并<v-footer>在三个不同的文件。

目前我正在使用。

Layout.vue

<template>
  <v-app>
    <TopNav :drawer="drawer" :clipped="clipped"></TopNav>
        <SideBar/>
        <v-content>
            <v-container fluid>
                <router-view></router-view>
            </v-container>
        </v-content>
        <FooterArea/>
    </v-app>
</template>

脚本Layout.vue

<script>
import { TopNav, FooterArea, SideBar } from "../layouts/index";

export default {
  name: "Full",
  components: {
    TopNav,
    FooterArea,
    SideBar
  },
  data() {
    return {
      clipped: true,
      drawer: true,
      fixed: false,
      inset: true,
      items: [
        {
          icon: "bubble_chart",
          title: "Inspire"
        }
      ],
      miniVariant: false,
      right: true,
      rightDrawer: false,
      title: "Vuetify.js"
    };
  }
};
</script> …

我试图从结构方程模型 (SEM) 中找到方差膨胀因子 (VIF)。我的模型是：

# load the data
library(readxl)
Log_And_SurveyResult <- read_excel("C:/Users/Aakash/Desktop/analysis/Today/Mot-Log.xlsx")

# load lavaan
library(lavaan)

#scale the variables
Log_And_SurveyResult$Time <-
scale(Log_And_SurveyResult$TotalActivity)

model <-
Ct =~ CT1 + CT2 + CT3
R =~ R1 + R2 + R3
B =~ B1 + B2 + B3
UserActivity =~ Time + TotalActivity

fit <- sem(model,data = Log_And_SurveyResult, std.lv = TRUE)
summary(fit, standardized=T)

这是我的数据示例：

Time,TotalActivity,CT1,CT2,CT3,R1,R2,R3,B1,B2,B3
-0.4923798,-0.09991485,4,4,4,3,3,3,3,3,2
-1.0519708,-1.12771752,3,2,2,2,2,3,4,2,3
-0.5330384,-0.06320762,4,4,5,5,4,4,4,4,4
-1.0134522,-0.67805386,5,4,4,5,5,4,4,5,5
-1.1568273,-1.18277838,4,3,4,3,2,3,3,4,4
-0.8561675,-0.12744528,3,4,4,4,4,3,3,3,3

当我运行时vif(fit)，出现错误：

Error: $ operator not defined for this S4 class …
