This function downloads the JAGS installer that matches the operating system and R version
(see cmsy_jags_versions() and cmsy_download_jags()), checks its size and checksums, and
opens it: the .exe installer on
Windows and the .pkg installer on macOS. On Linux it downloads the source code and shows
how to install JAGS with the package manager or from source. An installer placed in the
package folder inst/jags/ (installed as jags/) is used instead of downloading.
Usage
cmsy_install_jags(
version = "recommended",
os = "auto",
open = TRUE,
data_dir = fao_data_dir(),
silent = fao_setting("silent")
)Arguments
- version
The JAGS version: "recommended" (default), "latest" or a version number.
- os
The operating system whose settings are used: "auto" (default, detect it), "windows", "macos" or "linux".
- open
A logical value. If TRUE (default), the installer is opened.
- data_dir
The directory where downloads are kept. Default is
fao_data_dir().- silent
A logical value. If TRUE, no summary is printed. Default is FALSE, or the value set with
fao_settings(silent = ).
