First official CRAN release!
need()
(and is_installed()
) can check
for a minimum version of a package by appending
>=[version]
,
e.g. need("pkg>=0.1.2")
need()
also gains a couple of new arguments:
msg
to provide a custom informative message, to be
displayed to users if one or more packages will need to be
installedinstall_cmd
to provide a custom installation
command, which will be used in the installation promptneed()
now doesn’t load packages by default: instead it
checks whether a package has a valid installation location. This is much
faster, but slightly less of a guarantee that the package is actually
usable. You can switch back to the package-loading method with
load = TRUE
.
First package release.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
