如何在针织衫中打印表格 [英] how do you print table in knitr

问题描述

我正在尝试用knitr使用xtable以表格格式打印数据框:

I am trying to us knitr to print data frame in table format using xtable:

```{r xtable,fig.width=10, fig.height=8, message=FALSE, results = 'asis', echo=FALSE, warning=FALSE, fig.cap='long caption', fig.scap='short',tidy=FALSE}

print(xtable(d),format="markdown")
```

这是数据帧d:

d <- structure(list(Hostname = structure(c(8L, 8L, 9L, 5L, 6L, 7L, 
1L, 2L, 3L, 4L), .Label = c("db01", "db02", "farm01", "farm02", 
"tom01", "tom02", "tom03", "web01", "web03"), class = "factor"), 
    Date = structure(c(6L, 10L, 5L, 3L, 2L, 1L, 8L, 9L, 7L, 4L
    ), .Label = c("10/5/2015 1:15", "10/5/2015 1:30", "10/5/2015 2:15", 
    "10/5/2015 4:30", "10/5/2015 8:30", "10/5/2015 8:45", "10/6/2015 8:15", 
    "10/6/2015 8:30", "9/11/2015 5:00", "9/11/2015 6:00"), class = "factor"), 
    Cpubusy = c(31L, 20L, 30L, 20L, 18L, 20L, 41L, 21L, 29L, 
    24L), UsedPercentMemory = c(99L, 98L, 95L, 99L, 99L, 99L, 
    99L, 98L, 63L, 99L)), .Names = c("Hostname", "Date", "Cpubusy", 
"UsedPercentMemory"), class = "data.frame", row.names = c(NA, 
-10L))

有什么想法我在这里想念的吗?

Any ideas what I am missing here?

推荐答案

尝试使用knitr中的kable.它将很好地格式化表格.

Try kable from knitr. It will format the table nicely.

如果您想使用xtable，请尝试:

If you would like to use xtable try:

print(xtable(d), type="latex", comment=FALSE)
