How do I open a script file in RStudio using an R command?

I have a simple script file called test.R. It's saved in the working directory. When I go to File > Open > test.R, it opens the file in the editor (without executing the code, which is what I want).

How do I do this by typing a command in the console window? To be clear, I just want to open (not execute) the file.

Solution 1:

You are looking for file.edit

file.edit('test.R')

should open the file in an editor (if you are in RStudio, this should default to RStudio)

Solution 2:

It appears that if you are using RStudio then another option is to use rstudioapi::navigateToFile("test.R")

Solution 3:

Another alternative is the shell.exec function.

shell.exec("text.R") # This will open the file or URL using the path associated with it

Also, I think for your use case. This code snippet might be a little bit useful.

file <- "example.csv"
sub_dir <- "subdirectory"
dir.create(sub_dir)
writeLines("myfile",file.path(sub_dir, file))
# Works
shell.exec(file.path(sub_dir, file, fsep = "\\"))
shell.exec(file.path(sub_dir, file))
