在R中的Markdown文档中生成缓存对象的视图
我无法在降价文档中显示由不同R脚本(在同一会话中)生成的对象.我想指出，我是Markdown的新手.因此代码如下(在前后添加''):
I cannot show object in markdown document that are objects generated in different R script(within the same session). I would like to point out that I am newbie to markdown. So the code is as follows(''' are added before and after):
{r eval=TRUE, echo=FALSE}
head(output_by_size,10) # 1st line
summary(cars) # 2nd line
dim(iris) # 3rd line
{r eval=TRUE, echo=FALSE}
head(output_by_size,10) # 1st line
summary(cars) # 2nd line
dim(iris) # 3rd line
当我在第2和第3行添加注释时，会产生以下错误: 头错误(output_by_size，10):找不到对象'output_by_size' 调用:... withCallingHandlers-> withVisible-> eval-> eval-> head
when I comment line 2nd and 3rd the following error is generated: Error in head(output_by_size, 10) : object 'output_by_size' not found Calls: ... withCallingHandlers -> withVisible -> eval -> eval -> head
注释第一行时，第二行和第三行按预期工作. Output_by_size只是简单的数据框对象.你能帮我吗?
When 1st line is commented, lines 2nd and 3rd work as expected. Output_by_size is just simple data frame object. Could you please help me out?
有两种方法可以将数据"output_by_size"加载到您的.RMD文件中:
There are 2 ways to load the data "output_by_size" to your .RMD file:
-
不要使用Rstudio的编织"按钮来编织文件，保存RMD文件，然后使用控制台:
Don't knit your file with the Rstudio "knit" button, save your RMD file and then use the console:
library(knitr)
knit('your_file.Rmd')
这将考虑您最近的环境，并且错误应该消失了.
This will take your recent environment into account and the error should be gone.
将"output_by_size"存储为"output_by_size.RData"，并将其手动加载到RMD文件中
Store your "output_by_size" as "output_by_size.RData" and load it manually in your RMD file
```{r load myData, include=FALSE}
load("output_by_size.RData")
```
如果采用这种方式，则可以使用RStudio中的编织"按钮.
If you do it this way you can use the "knit" button from RStudio.
我希望其中一种方法对您来说是一个好的解决方案.
I hope one of this ways is a good solution for you.
