为什么我无法打印使用 knitr 包中的 kable 函数生成的正确输出?

Why am I unable to print the proper output produced using the kable function from the knitr package?

我一直在尝试使用 kable 函数打印数据字典。这是我的代码:

dict<-build_dict(my.data = tweets_train,linker=linker,option_description = NULL, prompt_varopts = T)
kable(dict,format="latex",caption="Data dictionary for the Training dataset") %>%
  kable_styling(position = "center")

这是输出:

> kable(dict,format="latex",caption="Data dictionary for the Training dataset") %>%
+   kable_styling(position = "center")

\begin{table}

\caption{\label{tab:}Data dictionary for the Training dataset}
\centering
\begin{tabular}[t]{l|l|l|l}
\hline
variable name & variable description & variable options & notes\
\hline
sentiment & Sentiment Score 0 for Negative sentences and 4 for Positive sentences & 0 to 4 & The polarity of the tweet (0 = negative, 2 = neutral, 4 = positive)\
\hline
text & The tweets collected & ''  oh u can take me to the game with u  mor  to zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz so tired   good night hokies & The dataset Sentiment 140 that originated from Stanford University for the purpose of Training\
\hline
\end{tabular}
\end{table}

我该如何纠正这个问题。第一次使用 knitr,因为我必须创建一个数据字典。任何建议将不胜感激。提前致谢。

这是@Marius 提到的转换代码的方法

你需要把它放在一个降价文件中,如下所示:

将其粘贴到 r 块中

dict<-build_dict(my.data = tweets_train,linker=linker,
                 option_description = NULL, prompt_varopts = T)
knitr::kable(dict,format="latex",caption="Data dictionary for the Training dataset") %>%
knitr::kable_styling(position = "center")  

像这样,将 knitr 放在 kable 之前以调用库本身(或在 library(knitr) 之前调用它):

然后保存并编织:) 希望有帮助
