 easiest way to do so is by creating a text file .Renviron in your 
 Documents folder which contains the following line:
 ```
-PATH="${RTOOLS40_HOME}\usr\bin;${PATH}"
+PATH="${RTOOLS44_HOME}\usr\bin;${PATH}"
 ```
 
 You can do this with a text editor, or from `R` like so (note that in 
 `R` code you need to escape backslashes):
 ```{r eval=FALSE}
-write('PATH="${RTOOLS40_HOME}\\usr\\bin;${PATH}"', file = "~/.Renviron", append = TRUE)
+write('PATH="${RTOOLS44_HOME}\\usr\\bin;${PATH}"', file = "~/.Renviron", append = TRUE)
 ```
 
 Restart R, and verify that make can be found, which should show the path
 to your Rtools installation.
 
 ```{r eval=FALSE}
