Incorrect number of dimensions

[Miguel0809]

Hello!

When I run the function

curr_rsi14_api <- function(x){
df <- rgdax::public_candles(product_id = "ETH-USD",
granularity = 900)
rsi_gdax <- tail(TTR::RSI(df[,5],
n = 14),
n = 1)
rsi_gdax
}

Show up a Error in Console of RStudio "Error in df[, 5] : incorrect number of dimensions".

What to do to fix the script?
