在RStudio的RStudio中运行块时，如何打印tibbles？
我无法通过在RStudio中的R笔记本中运行块来打印由下面的CSV文件创建的Tibble。下面的示例打印来自read_csv的有关解析的消息，但不打印df。然而，当我预览笔记本时，数据框就会被打印出来。当使用R控制台输入代码时，数据帧也被打印出来。

title: "Min Example"
output: html_notebook

```{r chunk}图书馆(重新登记)
图书馆(Tibble)
df <- read_csv('min.csv')
df
在运行块时，命令头(Df)也不会产生输出，但是汇总(Df)和str(df)确实会在笔记本中产生输出。
我正在使用最新版本的RStudio，1.0.136，我的软件包是最新的。我的会话信息如下

在另一个回答/问题(在这里)中，Kevin说：
这确实是RStudio当前版本中的一个错误:包含日期对象的data.frames在笔记本中没有正确呈现。您可以尝试安装最新的RStudio每日构建并确认问题在那里得到解决：http://dailies.rstudio.com
在升级或降级之间，可以使用print (as.matrix())在代码块中临时打印as.matrix：
```{r}打印(as.matrix(Df)，引号=假)
模拟头()的行为：
```{r}打印(as.matrix(Df)，引号= FALSE，max = length(df) * 6)
