我正在尝试合并以大量变量为特征的不同数据框，这些变量以c302，c303等代码命名。从SPSS导入的原始文件保持非常有用的标签。
当我尝试合并这些数据框时（使用cbind或merge），我丢失了所有变量标签。是否可以保留它们？
答案 0 :(得分：0)
不使用<div class='tabs'>
<h5>Tabs</h5>
</div>
<div class='content'>
<h5>Here is some random text to make this scroll</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
<h5>This is the main content</h5>
</div>
<div class='slide-up'>
<h5>Slide up content</h5>
<h5>Slide up content</h5>
<h5>Slide up content</h5>
<h5>Slide up content</h5>
<h5>Slide up content</h5>
<h5>Slide up content</h5>
<h5>Slide up content</h5>
<h5>Slide up content</h5>
<h5>Slide up content</h5>
<h5>Slide up content end</h5>
</div>，而是使用dplyr的merge，因为它保留了属性：
left_join
