Hi all,
I just installed a package using the GUI and install.packages( etc)
The I opened the terminal and ran R from there and tried to load the
package which
returned with an error saying the package was not available which
seemed strange to me.
?install.packages says that the default location for installing
packages is
.libPaths()[1]
but this turns out to be different in the GUI:
"/Users/ivisser/Library/R/2.7/library"
Apparently you told the GUI to set it, see R -> Preferences ->
Startup -> Default Library Paths
That setting is often used by users that either don't have admin
privileges or want to keep their set of packages separate from the
system ones. The default is off, so you must have enabled it at
some point.
Dear Simon and R mac fans,
After unsetting the default library paths option in the preferences
I get:
> .libPaths()[1]
[1] "/Library/Frameworks/R.framework/Versions/2.6/Resources/library"
And in the terminal I get:
> .libPaths()
[1] "/Library/Frameworks/R.framework/Resources/library"
After freshly installing 2.7.0 I get in the GUI:
> .libPaths()
[1] "/Library/Frameworks/R.framework/Versions/2.7/Resources/library"
And after setting the default lib path in the preferences pane:
[1] "/Users/ivisser/Library/R/2.7/library"
[2] "/Library/Frameworks/R.framework/Versions/2.7/Resources/library"
And in the terminal:
> .libPaths()
[1] "/Library/Frameworks/R.framework/Resources/library"
In the package install menu the default checked option is at "System
level" meaning in the R framework but it seems that that could still
be one of two possible paths, ie the versioned path from the GUI or
the unversioned path from the terminal.
They are both the same. The unversioned path is just a symlink to the
versioned path. The "real" location is always the versioned path.
Cheers,
Simon
