How to use objects from global environment in Rstudio Markdown (5 answers)

Closed 3 years ago.

I'm trying to use data from Global Environment in R Markdown. When I call a 'summary(mydata)' it gives me this error:

object 'mydata' not found

I got all my work in many different scripts, so that is not easy for me to create a .R file for each result.

So, can I call data defined on Global Environment in R Markdown?

Thank You.

There are 2 ways to load the data myData to your .RMD file:

1. Don't knit your file with the Rstudio "knit" button:

   library(knitr)
   knit('your_file.Rmd')
   

This will take your recent environment into account and the error should be gone.

2. Store your myData as "myData.RData" and load it manually in your RMD file

   ```{r load myData, include=FALSE}
   load("myData.RData")
   

   If you do it this way you can use the "knit" button from RStudio.

I hope one of this ways is a good solution for you.
