Package Dependency

Lately, I see a dependency problem with R-3.2 systems.
install.packages allows dependencies, but they are not installed so
the install fails.

I see this a lot with students who are able to install packages like
ggplot2 but then can't load it because a dependency "stringi" is
missing.  Those students are generally using Windows, but today I
reproduced the same on RedHat Linux with R-3.2.2.

desiredPackages is a big vector of packages to install. This is using
a trick that one of R Core taught me about 15 years ago...

+                                             lib = TARGETLIB)

However, I can manually install that individual package
+                                             dependencies = c("Depends"),
+                                             lib = TARGETLIB)

The downloaded source packages are in

After that, I start over,  the install of the desiredPackages vector
proceeds, but hits another snag:

install.packages(desiredPackages[!alreadyHave],
                                            dependencies = c("Depends"),

Go back, install just that one

I don't recall seeing this problem until the last few months.

You are saying you only want dependencies listed in the "Depends" field 
of DESCRIPTION.  Many packages nowadays have dependencies listed in 
"Imports", because that's now the recommended way to do it.  Those are 
not optional.

Imports are loaded, but don't affect the search path, so that's why 
they're preferred over Depends, which are both loaded and attached to 
the search path.  Modifying the search path can break user scripts.
