我想NAs在输出中省略与 doknitr::kable相同的输出xtable（参见下面kable的xtable输出）。

fm12anova <-
  structure(list(SOV = c("Days", "Residuals"), Df2 = c(1L, 178L
  ), Sum.Sq2 = c(162702.651909532, 405251.617480465), Mean.Sq2 = c(162702.651909532, 
  2276.69448022733), F.value2 = c(71.4644205986244, NA), Pr..F.2 = c(9.89409632221545e-15, 
  NA), Sum.Sq1 = c(30031.0139578738, NA), Mean.Sq1 = c(30031.0139578738, 
  NA), NumDF1 = c(1L, NA), DenDF1 = c(17.0000010028433, NA), F.value1 = c(45.8530037127448, 
  NA), Pr..F.1 = c(3.26378804516025e-06, NA)), class = "data.frame", row.names = c(NA, 
  -2L), .Names = c("SOV", "Df2", "Sum.Sq2", "Mean.Sq2", "F.value2", 
  "Pr..F.2", "Sum.Sq1", "Mean.Sq1", "NumDF1", "DenDF1", "F.value1", 
  "Pr..F.1"))

library(knitr)
kable(fm12anova)

在 knitr 中打印数据帧时，请查看 svannoy 关于 隐藏 NA 的答案

```{r echo=FALSE, results='asis'}
options(knitr.kable.NA = '')
knitr::kable(lowerTri, digits=2)
```

（试图标记为可能的骗子，但我是个菜鸟。）
