Question

我在通过降价将此文件另存为pdf时遇到问题。一切都节省下来，直到我到达hist()的块，我得到错误closure is not subsettable withCallingHandlers -> withVisible-> eval ->hist我试着环顾四周并检查变量/对象是否保存为常用函数。任何帮助都会很好！

```{r eval=FALSE}  
Study<-read.csv("Data.csv")
```

Recode Age column into oridinal variable and store into new column
```{r eval=FALSE} 
Study$Age2 <- as.factor( # Define new column as a factor/categorical variable
  case_when(Study$s1 <= 65 ~ 'Young-Old',
            between(Study$s1, 66, 75) ~ 'Med-Old',
            between(Study$s1, 76, 85) ~ 'Old',
            Study$s1 >= 86 ~ 'Old-Old'
  )
)
```
Conduct histogram to illustrate patients' age distribution
```{r, echo=FALSE}
hist(as.numeric(Study$Age2), main = "Age Distribution", xlab = "Age Range")
```

Answer 1

您的问题是，前两个代码块未被评估，因此数据不适用于块＃3。因此，如果您将代码更改为

```{r}  
Study<-read.csv("Data.csv")
```

Recode Age column into oridinal variable and store into new column
```{r} 
Study$Age2 <- as.factor( # Define new column as a factor/categorical variable
 case_when(Study$s1 <= 65 ~ 'Young-Old',
            between(Study$s1, 66, 75) ~ 'Med-Old',
            between(Study$s1, 76, 85) ~ 'Old',
            Study$s1 >= 86 ~ 'Old-Old'
  )
)
```

渲染过程完全运行。

然而，这个问题很奇怪，因为r和eval = F之间没有逗号，所以eval = F是块的名称，但也不会被计算。如果您不想在输出文件中包含代码，可以添加{r, include = F}。
