Load/unload one or more packages. When loading one or more packages, if not already installed, try install it/them from various repos. If url is assigned, the package will also be downloaded and installed from that alternative url.

loadPkgs(..., repo = c("cran", "c", "github", "g", "gh", "gitlab", "l",
  "gl", "bioconductor", "bioc", "b", "bitbucket", "k", "omegahat", "oh",
  "o"), url = NULL, quiet = TRUE)

unloadPkgs(..., force = FALSE, quiet = FALSE)

`...`	Strings or expressions representing packages to load/install or unload. In the function `unloadPkgs`, if `...` is not assigned, then all the non-default packages (base, methods, datasets, utils, grDevices, graphics, stats) will be unloaded.
`repo`	Currently only accepts 'cran'/'c', 'github'/'gh'/'g', 'gitlab'/'gl'/'l', 'bioconductor'/'bioc'/'b', 'bitbucket'/'k', and 'omegahat'/'oh'/'o'. Refer to Details.
`url`	If any of `pkgs` was not installed yet, and `url` is specified, `loadPkgs` will try to download and install the package from that url (It must point to a valid file on internet). Default to NULL.
`quiet`	Logical, default TRUE for `loadPkgs` and FALSE for unloadPkgs. If TRUE, the packages will be installed/loaded or unloaded(detached) quietly.
`force`	Logical. Should a package be detached even though other attached packages depend on it?

There are several groups of repos that you can apply:

c: c or cran, you can also use install.packages()
g: g or gh or github, you can also use remotes:: install_github
b: b or bioc or bioconductor, you can also use remotes:: install_bioc
k: k or bitbucket, you can also use remotes:: install_bitbucket
l: l or gl or gitlab, you can also use remotes:: install_gitlab
o: o or oh or omegahat, you can also use install.packages with repos='http://www.omegahat.org/R', type="source"

When you don't want to use the repo, you can directly assign url to download and install the pacakge(s).

invisible. If you set quiet = FALSE, the verbose information will be printed out.
