Question

我正在使用Rstudio版本1.1.447。在使用Windows 10的Dell Latitude E5470上。我正在尝试使用R markdown和knittr以及ioslides为作业创建演示文稿。结果演示文稿具有完整的黑页而不是图表。但是，如果我在R markdown之外运行代码，那么图表会显示在Rstudio中。

这是我的代码：

```{r, echo = TRUE, include=FALSE}
library("plotly")
library("ggplot2")
library("datasets")
data("state")

x <- state.area
y <- state.x77[,1]*1000
z <- state.x77[,5]
fac <- state.division

newdf <- as.data.frame(cbind(state.area, state.x77[,1]*1000, state.x77[,5], state.division))
colnames(newdf) <- c("Area", "Population", "Murder", "Division")

p <-plot_ly(newdf, 
            x="Area", 
        y="Population",
        z="Murder",
        type="scatter3d", 
        mode="markers", 
        color="Division")
p
```

尝试相同但删除{r, echo = TRUE, include=FALSE}并将其替换为{r}。

这是一个完整的工作答案。

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)

library("plotly")
library("ggplot2")
library("datasets")

data("state")

x <- state.area
y <- state.x77[,1]*1000
z <- state.x77[,5]
fac <- state.division
```

Awesome comments about plot output goes here:

```{r}

newdf <- as.data.frame(cbind(state.area, state.x77[,1]*1000, state.x77[,5],     state.division))
colnames(newdf) <- c("Area", "Population", "Murder", "Division")

p <-plot_ly(newdf, 
            x="Area", 
        y="Population",
        z="Murder",
        type="scatter3d", 
        mode="markers", 
        color="Division")
p
```

R Markdown不显示图形图形
