Error:subscript out of bounds: no column name containing "Close

I have downloaded the time series of crude oil in to R ( from a local excel
file(csv/text tab delimited) in C drive)and the data ( OHLC) is being
displayed in my R.Studio.
Am able to ascertain the Fibonacci pivot levels ( using a custom program
that I have developed). But when I use package Quantmod and try to
calculate the values using MACD,RSI etc,I get an error  *subscript out of
bounds: no column name containing "Close" *
I googled and found that many R users have  asked help for this issue in
the past.By and large this question looks to be remaining unresolved.
Can you please help me with a solution?

You haven't provided a minimal reproducible example, or nearly enough 
data to answer your question with certainty.


For the purposes of my guestimate, we'll assume your variable is called 'x'

I suspect that your 'OHLC' data doesn't contain any columns that 
quantmod's OHLC utility functions can recognize as close data.

Check the column names of your data.

Try using quantmod functions such as Cl(x) or is.OHLC(x) to see if 
quantmod recognizes your column names. (They are looking for variations 
of English words such as 'open, 'high', 'low', and 'close', 
capitalization unimportant)

The TTR functions MACD and RSI expect univariate data, not OHLC data, as 
is noted in the documentation.  You could try something like:

RSI(getPrice(x))
MACD(getPrice(x))

and the quantmod function 'getPrice' will try to guess at a column that 
may contain price data.  This may suffer from the same problem as above.

In short, your problem is almost certainly that the column names of your 
imported data are unintelligible:  Check this first.

If you're still having trouble, please follow the posting guide and 
provide a minimal reproducible example.
