Looks normal to me. Setting relating to history seem OK. Should I send
you personally a screen shot? I don't think I can attach an image for
the whole forum. In Preferences, the history file was listed as
.Rhistory. I tried to change this to ~/.Rhistory, but when I closed R
and reopened it, it reverted to .Rhistory.

I got a large number of hits. I recognized all the directories as
directories which had been, at one time or another, possibly with a
different version of R, the working directory for some R program. I
deleted all these hits as confusing the issue. I found one .Rhistory
in the working directory, containing a single command that I almost
certainly gave some time today. At some point today I deleted this
file and it has been re-created with this single command in it.
Nevertheless, history() continues to give me a blank screen. If things
were operating as I wish, there would have been many commands
in .Rhistory, since I have typed many commands to the R console today.
