对于几个对应分析包，单个plot函数生成多个图。第一个图是active，其余的是inactive。有没有办法在knitr html输出中一个接一个地打印所有图。我正在尝试以下，这是行不通的。
```{r fig.keep='all'}
library(CAvariants)
data(asbestos)
head(asbestos)
str(asbestos)
CAvariants(asbestos, catype = "CA", firstaxis = 1, lastaxis = 2)
CAvariants(asbestos, catype = "DOCA", firstaxis = 1,lastaxis = 2)
CAvariants(asbestos, catype = "DONSCA",firstaxis=1, lastaxis = 2, ellcomp = FALSE)
risasbestos<-CAvariants(asbestos, catype = "DOCA", firstaxis=1, lastaxis=2)
plot(risasbestos, plotype = "biplot", biptype = "row")
```
函数plot.CAvariant有几个对dev.new（）的调用，knitr处理得不好。您可以做的是手动编辑该功能以删除这些调用，如下所示：
