I was in the middle of making an R markdown document when all my code chunks started returning the same error "is not recognized as an internal or external command, operable program or batch file." What’s going on here?
example:
"""
“{test}
2 + 2
“
‘test’ is not recognized as an internal or external command,
operable program or batch file.
"""
I opened a separate R markdown I had made previously and had no issues running any chunks.
>Solution :
It looks like you’re missing the r at the start of the code chunk definition. Each code chunk should always start with three backticks then r and then the label.
e.g.
```{r test}
2 + 2
```
