How no more install y/n prompts in R for unsupervised experimentation?

Question

I am testing most of the models caret supports on a bunch of PCs. Unfortunately caret "suggested" packages do not include most of the model packages available to caret. Every time a new version of R comes out I have to sit in front of each PC and wait for each prompt to press the 1 button and Enter. Is there an option I could set to tell R or Rstudio to just install anything asked for? A for every a/s/n prompt too.

list.of.packages <- c("caretEnsemble","logicFS"," RWeka","ordinalNet","xgboost","mlr","caret","MLmetrics","bartMachine","spikeslab","party","rqPen","monomvn","foba","logicFS","rPython","qrnn","randomGLM","msaenet","Rborist","relaxo","ordinalNet","rrf","frbs","extraTrees","ipred","elasticnet","bst","brnn","Boruta","arm","elmNN","evtree","extraTrees","deepnet","kknn","KRLS","RSNNS","partDSA","plsRglm","quantregForest","ranger","inTrees")


new.packages <- list.of.packages[!(list.of.packages %in% installed.packages()[,"Package"])]
if(length(new.packages)) install.packages(new.packages, dep = TRUE)


install.packages("mlr", dependencies = c("Depends", "Suggests"))
install.packages("caret", dependencies = c("Depends", "Suggests"))

Code I went with:

 list.of.packages <-getModelInfo(allmodel)[[1]]$library;
new.packages <- list.of.packages[!(list.of.packages %in% installed.packages()[,"Package"])];
if(length(new.packages)) install.packages(new.packages, dep = TRUE)

This code:

getPackages <- function(packs){
  packages <- unlist(
    tools::package_dependencies(packs, available.packages(),
                                which=c("Depends", "Imports", "Suggests"), # 
                                recursive=TRUE)
  )
  packages <- union(packs, packages)
  packages
}

packages <- getPackages(c("caret")) # add in other packages you want here
install.packages(packages)

from https://stackoverflow.com/a/15650828/6619250 allows you to install all dependencies (recursively) from "Depends", "Imports", and "Suggests"

However, actually trying out this code results in a list of 959 (!!) packages because of the list of 'Suggests' packages.

Hence, I would advice you to take a look at the list of "Suggests" packages in CRAN and replace caret with your own list, which you will have to do go through yourself to determine which packages you want.
