Week 1 - Installing packages

[zyaseen-cpu]

Hi,

I'm not sure what I'm missing, but I cant seem to run code in Positron?

Hmmm @zyaseen-cpu, this looks puzzling.

If you reopen Positron, can you see the following:

If you are seeing them, you should be able to run code. For your Install Packages.R script, if you click on the individual line (install.packages("purrr")) and run it (via Ctrl + Enter on the keyboard) does it go to console and produce any output?

Alternatively, can you copy and paste this into your console and hit enter?

install.packages("purrr")

If those run, it is likely something about your attempt to source the file while within the file didn't quite work out.

If still not working, what you could try would be to kill the R session from the console window, and then re-initialize it via the interpretor:

Let me know if any of these options work.

Also, it is best to do your editing outside the CytometryInR folder you are currently in. The Week1 folder is likely to cause issues down the road, since when you try to pull in new data each week, the extra folder is not accounted for on the course project side, and will cause an error to be returned. It is best to start a new project folder
) separate to the CytometryInR folder to avoid this issue

Hi David,

Thanks for the reply. I've noticed that when I select 'Start Session' and choose R, it doesn't work

[DavidRach]

Hmm, so definitely a bad R installation. What's your computer's operating system? It could be as simple as you accidentally installed the x86_64 version when you have an ARM-based CPU or vice versa. The alternate could be it is installed in an odd location?

One thing you can try, is run the following in the terminal tab next to the console tab:

quarto check

And take a screenshot.

Hi @zyaseen-cpu, yeah, looks like you have a Mac M1 (ARM-based chip), but installed the R for x86_64 (Intel-style chip). I would uninstall R, and attempt to reinstall. The option you want to select is the following:

Once you have reinstalled R, reopen Positron and see if it starts working.
