最大化R中gvisTimeline的高度

Question

如何在 R 中最大化 gvisTimeline 的高度

我的代码：

 datTL <- data.frame(Position=c(rep("President", 5), rep("Vice", 5)),
                Name=c("Washington", "Adams", "Jefferson",
                       "Adams", "Jefferson", 
 "Burr","Washington2","Washington22","Washington33","Washington44"),
                start=as.Date(x=rep(c("1789-03-29", "1797-02-03", 
                                      "1801-02-03", "1800-01-01","1850-01-01"),2)),
                end=as.Date(x=rep(c("1797-02-03", "1801-02-03", 
                                    "1809-02-03","1830-02-03","1890-02-03"),2))
              )

 Timeline <- gvisTimeline(datTL, 
                     rowlabel="Name",
                     barlabel="Position",
                     start="start", 
                     end="end",
                     options=list(        width = "automatic",
                                  height = "automatic" )   )
plot(Timeline)

查看输出

您必须提供具体的身高数字
一种常见的做法是select一个行高，
然后乘以数据中的行数 table。

var rowHeight = 44;
var options = {
  height: (dataTable.getNumberOfRows() * rowHeight) + rowHeight  // <-- adder for heading
};
