R normally prompts you to save .RData, but it just automatically
saves .Rhistory... the two are unrelated.
Not here. If I say "n" to the prompted question "Save workspace image?
[y/n/c]: " my history doesn't get saved.

On Windoze, here's what I use in my .Rprofile, which runs every time I
start an RGUI coonsole. The key is .First & .Last to load/save
history automagically. There is some extra overhead in my use of
old.packages() here, but that is for a different reason.
### History
# could use Sys.getenv("R_HISTFILE")
# Sys.getenv("R_HISTSIZE"=1024)
.First <- function() {
if(interactive()) {
if (.Platform$GUI == "Rgui") {
histfile <- if (file.exists(".Rhistory")) ".Rhistory" else
"c:/R/.Rhistory"
try(utils::loadhistory(histfile))
old <- utils::old.packages()
if (! is.null(old)) cat("Updatable packages: ", old[,1], "\n",
fill=TRUE) else cat("All packages up to date\n")
}
setwd("c:/R")
cat(paste("[.Rprofile loaded, current dir:", getwd(),
"]\n"),sep=" ")
}
}
.Last <- function()
if(interactive() && .Platform$GUI == "Rgui") {
histfile <- if (file.exists(".Rhistory")) ".Rhistory" else
"c:/R/.Rhistory"
try(utils::savehistory(histfile))
}
