Description

Usage

install_megadepth(version = "latest", force = FALSE)

Arguments

version	A character()' specifying the Megadepth version number, e.g., 1.0.4; the special value latest means the latest version (fetched from Github releases).
force	A logical(1) specifying whether to install megadepth even if it has already been installed.

Details

This function tries to install Megadepth to Sys.getenv('APPDATA') on Windows, ‘~/Library/Application Support’ on macOS, and ‘~/bin/’ on other platforms (such as Linux). If these directories are not writable, the package directory ‘Megadepth’ of megadepth will be used. If it still fails, you have to install Megadepth by yourself and make sure it can be found via the environment variable PATH.

If you want to install Megadepth to a custom path, you can set the global option megadepth.dir to a directory to store the Megadepth executable before you call install_megadepth(), e.g., options(megadepth.hugo.dir = '~/Downloads/Megadepth_1.0.4/'). This may be useful for you to use a specific version of Megadepth for a specific project. You can set this option per project, similar to how blogdown.hugo.dir is used for specifying the directory for Hugo in the blogdown package.. See Section 1.4 Global options for details, or store a copy of Megadepth on a USB Flash drive along with your project code.

Value

Returns NULL. The main use is to install Megadepth.

References

This function is based on blogdown::install_hugo() which is available from https://github.com/rstudio/blogdown/blob/master/R/install.R.
