rscript_dir

Details

MODIStsp can be used also as a stand-alone tool (i.e., without opening RStudio or R-GUI) by launching a bash/batch script, which is stored in the installation folder (/ExtData/Launcher) To allow to easily find it, this function creates a desktop entry and a symbolic link to the bash script (on Linux) or a link in the Start Menu to the batch script and a shortcut on the desktop (on Windows). Note that, if the packages MODIStsp is installed in a version-dependent directory (as the default one is), this function should be re-executed after an R upgrade, otherwise the links would continue to point to the old package version!

Examples

# Linux: common installation (script in /usr/bin,
# desktop entry in /usr/share/applications)
# (requires administrator permissions)
if (FALSE) {
# the administrator password is asked interactively
install_MODIStsp_launcher(sudo = TRUE)
}

# Linux: installation in a directory which does not require administrator
# permissions
if (FALSE) {
install_MODIStsp_launcher(bin_dir = "~/bin", desktop_dir = "~/Desktop")
}

# Windows: common installation
# (script in the Start Menu and shortcut on the desktop)
if (FALSE) {
install_MODIStsp_launcher()
}
