Error "attempt to set an attribute on NULL" when calling getSymbols() for dates with no data #405

Open feelosophy13 opened 11 months ago

feelosophy13 commented 11 months ago

Description

When I call getSymbols() for a date for which there is no data, it throws an error.

Expected behavior

Should return an empty data frame.

Minimal, reproducible example

> library(quantmod)
>
> ## trying to get saturday and sunday data
> a = getSymbols(
        'AAPL', 
        src='yahoo', 
        from='2023-11-04',  # saturday (inclusive)
        to='2023-11-06',  # monday (exclusive)
        auto.assign=FALSE
   )
Error in getSymbols.yahoo(Symbols = "AAPL", env = <environment>, verbose = FALSE,  : 
  Unable to import “AAPL”.
