If you can get a vector with all the package names (I do not know how to do
this) then you could do something like this;
# Function to check and install missing packages
install_if_missing <- function(pkg) {
if (!require(pkg, character.only = TRUE)) {
install.packages(pkg, dependencies = TRUE)
}
library(pkg, character.only = TRUE)
}
# List of required packages.
packages <- c("emmeans", "multcomp", "sandwich", "multcompView", "ggplot2",
"stringr", "dplyr", "openxlsx", "tidyr")
# Check and install each package
lapply(packages, install_if_missing)

Tim

Hi folks:
Curious question. I've added Rcmdr to my setup (R 4.4.1). I would like to add
all of the plugins. Is there a way to get install.packages() to gather up
everything starting 'rcmdrplugin', or do I have to list each package
individually between the brackets?? 😕️
Regards...
