Can Only Get 5 Days of Data on Stock Index R

I have a script to download data from yahoo-finance into R. It works well for every stock, but has a hard time with indexes. I am trying to run the index TNX, but It only gives me data from 5 consecutive days.

I've tried putting a "^" before the index, because that is what yahoo finance uses as a variable for indexes, and it doesn't work.

ticker <- "TNX"
start.date <- as.Date('2016-09-01')
getSymbols(ticker, src='yahoo', from=start.date)
Adj.Close <- get(ticker)[,6]
daily.returns <- ROC(Adj.Close, n=1, type='continuous')

When I put this in I get no errors, but when I view daily. returns I get this:

2019-04-22  NA
2019-04-23  -0.03306086
2019-04-24  0.00000000
2019-04-25  -0.03419136
2019-04-26  0.00000000

That's all. Of course, this code works very well on any other stocks, but I just can't figure out this one.

Thank you for your time, and even if you can't help, your desire to help is appreciated.

You're getting all the data that Yahoo has:

You are using a ticker symbol that has been delisted that Yahoo hasn't completely unplugged.
