Re: [R] How to start R with a file loaded?

Thanks for your reply.

Indeed, I'm on Linux.

I tried to do what you said, but nothing happened.

I made a file called First.R in my work directory. It contains this code

  cat("it worked.")

I then source("First.R"), ok. and quit R. WhenI restart, nothing happens - maybe because I didn't save the image?

But I don't want to have to save the image, I want to make a dynamic startup of R with a file loaded, and execute a function call.

I alse tried this approach:

$ R < file.r

it seems to load, almost, then R quits.

Any ideas?

Thanks for your help in any case!
