Error: could not find function "chooseCRANmirror"

I use R on via the terminal on macOS Catalina. I had run into issues installing libraries, e.g.

> install.packages("caret")
Warning: unable to access index for repository http://cran.revolutionanalytics.com/src/contrib:
  cannot open URL 'http://cran.revolutionanalytics.com/src/contrib/PACKAGES'
Warning: unable to access index for repository http://cran.revolutionanalytics.com/bin/macosx/el-capitan/contrib/3.6:
  cannot open URL 'http://cran.revolutionanalytics.com/bin/macosx/el-capitan/contrib/3.6/PACKAGES'
Warning message:
package ‘caret’ is not available (for R version 3.6.0)

This issue can be solved by:

chooseCRANmirror(12)

I added that line to my ~/.Rprofile so that it auto-loads it at the start of every session. However, that returns:

Error: could not find function "chooseCRANmirror" [Previously saved workspace restored]

, and doesn't load the R profile, even though it works when I put it directly into my console. Why is this? And is there a solution to auto chooseCRANmirror(12) without having to manually do it each session?

Here is the rest of my ~/.Rprofile:

local({r <- getOption("repos")
      r["CRAN"] <- "http://cran.revolutionanalytics.com"
      options(repos=r)})
chooseCRANmirror(12)

options(stringsAsFactors=FALSE)
 
options(max.print=100)
 
options(scipen=10)
 
options(editor="vim")
 
# options(show.signif.stars=FALSE)
 
options(menu.graphics=FALSE)
 
options(prompt="> ")
options(continue="... ")
 
options(width = 80)
 
q <- function (save="no", ...) {
  quit(save=save, ...)
}
 
utils::rc.settings(ipck=TRUE)
 
.First <- function(){
  if(interactive()){
    library(utils)
    timestamp(,prefix=paste("##------ [",getwd(),"] ",sep=""))
 
  }
}
 
.Last <- function(){
  if(interactive()){
    hist_file <- Sys.getenv("R_HISTFILE")
    if(hist_file=="") hist_file <- "~/.RHistory"
    savehistory(hist_file)
  }
}
 
if(Sys.getenv("TERM") == "xterm-256color")
  library("colorout")
 
sshhh <- function(a.package){
  suppressWarnings(suppressPackageStartupMessages(
    library(a.package, character.only=TRUE)))
}
 
auto.loads = c("viridis", "tidyverse", "data.table")
 
if(interactive()){
  invisible(sapply(auto.loads, sshhh))
}
 
.env <- new.env()
attach(.env)
 
.env$unrowname <- function(x) {
  rownames(x) <- NULL
  x
}
 
.env$unfactor <- function(df){
  id <- sapply(df, is.factor)
  df[id] <- lapply(df[id], as.character)
  df
}

You need to specify the package.

utils::chooseCRANmirror(12)

.Rprofile only loads the base package. See ?Startup.

Note that when the site and user profile files are sourced only the base package is loaded, so objects in other packages need to be referred to by e.g. utils::dump.frames or after explicitly loading the package concerned.
