有没有一种方法可以使用RStudio直接在您的工作空间中进行降价促销? [英] Is there a way to knitr markdown straight out of your workspace using RStudio?

问题描述

我想知道是否可以使用knitr降价功能仅使用当前工作空间中的对象动态创建报告.可重复性不是这里的问题.我也阅读了很好的这里的线程 .

I wonder whether I can use knitr markdown to just create a report on the fly with objects stemming from my current workspace. Reproducibility is not the issue here. I also read this very fine thread here.

但是我仍然收到一条错误消息，抱怨找不到特定的对象.

But still I get an error message complaining that the particular object could not be found.

1)假设我打开了一个新的降价文档并保存了.

1) Suppose I open a fresh markdown document and save it.

2)编写一个块，该块引用我的工作空间中的某些lm对象.致电summary(mylmobject)

2) write a chunk that refers to some lm object in my workspace. call summary(mylmobject)

3)编织它.

不幸的是，生成了报告，但是由于找不到对象，因此无法显示回归输出.请注意，如果我只是将对象保存到.Rdata，然后直接从markdown文件中加载它，则它通常可以正常工作.

Unfortunately the report is generated but the regression output cannot be shown because the object could not be found. Note, it works in general if i just save the object to .Rdata and then load it directly from the markdown file.

有没有一种方法可以使用当前工作空间中R降价的对象? 向非R人员显示一些仍在工作的输出，这真是太好了.

Is there a way to use objects in R markdown that are in the current workspace? This would be really nice to show non R people some output while still working.

推荐答案

RStudio为knit()您的R Markdown文件打开一个 new R会话，因此当前工作空间中的对象将不会可用于该会话(它们是两个单独的会话).两种解决方案:

RStudio opens a new R session to knit() your R Markdown file, so the objects in your current working space will not be available to that session (they are two separate sessions). Two solutions:

1. 向RStudio提交功能请求，要求他们在当前R中支持编织会话，而不是强制开始新的会话；
2. 自己手工编织:library(knitr); knit('your_file.Rmd')(如果要一步输出HTML，则为knit2html()，如果使用rmarkdown::render())rel = "noreferrer"> R Markdown v2 )

1. file a feature request to RStudio, asking them to support knitting in the current R session instead of forcibly starting a new session;
2. knit manually by yourself: library(knitr); knit('your_file.Rmd') (or knit2html() if you want HTML output in one step, or rmarkdown::render() if you are using R Markdown v2)
