```{r message=FALSE, results = 'asis', echo=FALSE, warning=FALSE, fig.width=12, fig.height=10}

库(Xtable)

glossary2<-data.frame(names=letters1:4，definition=c(“超长文本”，“超长文本”)，include=c(NA，"YES"，NA，"NO"))

glossaryprin<-xtable(glossary2，label="tab:codebook"，caption="glossary")

align(glossaryprin)<-"lp{2in}p{3in}p{1in}“#更改如下

打印(glossaryprin，tabular.environment="longtable"，floating=FALSE，size="\fontsize{30pt}{10pt}\selectfont")

我可以在xtable输出表之外去掉{和}吗？

Answer 1

df <- gsub('[{}]', '', df)

这就是你要找的吗？
