更改R Markdown图形宽度

Question

我一直在尝试使用“ timevis”包创建事件的时间表并生成pdf。但是，我无法调整图形的大小以适合pdf宽度的100％，也无法删除绘图上的放大按钮。

```{r}
library(tibble)
library(timevis)
data <- tribble(~id, ~content, ~start, ~end,
                1,  "CSS 1", "1996-12-17", NA, 
                2,  "CSS 2", "1998-05-01", NA, 
                3,  "CSS 3", "1999-06-01", NA, 
                4,   "HTML", "1989-01-01", NA, 
                5, "HTML 2", "1995-11-24", NA, 
                6, "HTML 3", "1997-01-14", NA, 
                7, "HTML 4", "1997-12-18", NA,
                8, "HTML 5", "2014-10-28", NA, 
                9,    "CSS", "1994-10-10", NA, 
                10,    "JS", "1995-12-04", NA)

timevis(data)
```
