istate CRAN mirror not working - unable to use .Rprofile to change

I started getting errors installing packages using my default repository instate?

Warning: unable to access index for repository http://streaming.stat.iastate.edu/CRAN/src/contrib:
  cannot open URL 'http://streaming.stat.iastate.edu/CRAN/src/contrib/PACKAGES'
Warning: unable to access index for repository http://streaming.stat.iastate.edu/CRAN/bin/macosx/el-capitan/contrib/3.4:
  cannot open URL 'http://streaming.stat.iastate.edu/CRAN/bin/macosx/el-capitan/contrib/3.4/PACKAGES'
Warning message:
package ?RWeka? is not available (for R version 3.4.0)

Googling, I was able to do this using a different mirror selected with chooseCRANmirror(), I chose Kansas.

I googled how to make this the new default and was pointed to .Rprofile.
This doesn?t seem able to do this, with?

message(".Rprofile")
local({r <- getOption("repos")
      r["CRAN"] <- "https://rweb.crmda.ku.edu/cran"
      options(repos=r)})

I get?

Type 'demo()' for some demos, 'help()' for on-line help, or
'help.start()' for an HTML browser interface to help.
Type 'q()' to quit R.

.Rprofile
[R.app GUI 1.70 (7338) x86_64-apple-darwin15.6.0]

[History restored from /Users/mjh/.Rapp.history]

Which shows the ?.Rprofile? message indicating it has run.
However?

r <- getOption("repos")
r

                                    CRAN
"http://streaming.stat.iastate.edu/CRAN"

Still shows iastate.
Then doing?

source(".Rprofile")

.Rprofile

r <- getOption("repos")
r

                            CRAN
"https://rweb.crmda.ku.edu/cran?

so the .Rprofile does work. R must be changing it to iastate after the profile is run?
I had googled a mailing list thread where it was said .Rprofile wasn?t working on OS X. It was suggested in there that this be posted to this list. I checked the archives for the last couple months but didn?t see any mention.

Is this a problem that needs addressing? Or has a workaround besides sourcing .Rprofile whenever I want to install packages?
