R新手在这里。我目前正在尝试重新编码R中的一组变量,以便将其中的所有负值都重新编码为正值。
请在下面找到模拟数据:
<androidx.drawerlayout.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorActivityBackground"
android:descendantFocusability="beforeDescendants"
android:focusableInTouchMode="true"
android:layoutDirection="locale"
android:orientation="vertical"
android:textDirection="locale">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.appcompat.widget.Toolbar
android:id="@+id/topbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/colorPrimary"
app:contentInsetEnd="0dp"
app:contentInsetLeft="0dp"
app:contentInsetRight="0dp"
app:contentInsetStart="0dp"/>
</RelativeLayout>
</FrameLayout>
<com.google.android.material.navigation.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
android:maxWidth="320dp">
<ExpandableListView
android:id="@+id/navList"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:animateLayoutChanges="true"
android:background="@color/white"
android:groupIndicator="@null" />
</com.google.android.material.navigation.NavigationView>
</androidx.drawerlayout.widget.DrawerLayout>
这是我到目前为止编写的函数:
- hosts: myserver
become: yes
tasks:
- name: pull changes
shell: chdir=/path/whereis/myrepo git pull https://mygituser:mypassword@bitbucket.org/company/myrepo.git master
尽管我收到以下错误:
df <- data.frame(ID = c(1001, 1002, 1003, 1004, 1005, 1006, 1007, 1008, 1009, 1010, 1011),
measure1 = rnorm(11, mean = 0, sd = 1),
measure2 = rnorm(11, mean = 0, sd = 1),
measure3 = rnorm(11, mean = 0, sd = 1),
measure4 = rnorm(11, mean = 0, sd = 1))
关于如何进行这项工作的任何想法?
谢谢!
答案 0 :(得分:4)
您可以使用
df[, 2:5] <- abs(df[, 2:5])
