Hi Dave,
I've also had problems with the Package manager. I haven't figured out how to use packages that I've downloaded directly from the cran website.

It's not clear if these are source or binary packages.

I found another way of doing it instead: in the R Package Installer, choose CRAN (sources). Then click "Get List". You can install packages from the list (with location set to "At system level"). Then they load just fine using the load() function in the command window.

I hope this helps. If someone else knows of another way to install downloaded packages, I would be interested to learn because it has caused me some frustration.

Can you be more specific, please? Neither of you has described a problem with the packages - the Package Manager is there primarily to browse the documentation, not install packages... If you have problem installing packages, please tell us exactly what you're doing and what errors you get ...

It seems likely that

install.packages("<path/to/downloaded/file>", repos=NULL)

is what Mollie is looking for (works for source or binary packages, but for source packages you currently need to add 'type="source"'). If you want to use a GUI to choose a file, perhaps

install.packages(file.choose(), repos=NULL)


Cheers,
Simon

Greetings,
My apologies if this is a very simple question. I downloaded and installed a couple of packages today. In the package manager in R for Mac (version 2.7.2), I find that when I try to load the package, I can't. The load button never clicks on. Why is that? As an example, I'm trying to use Ryacas. Thanks in advance,
David
