Rmarkdown：Duplicate chunk label ‘plot’, which has been used for the chunk:

Error in parse_block(g[-1], g[1], params.src, markdown_mode) : Duplicate chunk label ‘plot’, which has been used for the chunk:
原因：我有两个绘图代码块，但没有命名，系统认为两个代码块是同名的，所以报错。

```{r plot}
plot(x,sqrt(x^(-m))*fit1$residuals,main="残差图")

```{r plot}
plot(x,sqrt(x^(-m))*fit2$residuals,main="残差图")

解决办法为：在{r plot}里加上命名，如下：
```{r plot1 plot}
plot(x,sqrt(x^(-m))*fit2$residuals,main="残差图")

```{r plot2 plot}
plot(x,sqrt(x^(-m))*fit1$residuals,main="残差图")
