[R-SIG-Finance] as.journal returns subscript out of bounds

[Arnaud Gaboury]

Even in a new empty environment, anf after a rebuild of ally my data
frames which bring me to the final ones, I still get this error:
gabx using magnolia [R] btc_journal <- as.journal(btc_op)
gabx using magnolia [R] View(btc_journal)
Error in names[[i]] : subscript out of bounds
gabx using magnolia [R] str(btc_journal)
‘journal’:	 78 transactions
 $ instrument: chr [1:78] "BTCUSDC" "BTCUSDC" "BTCUSDC" "BTCUSDC" ...
 $ timestamp : POSIXct[1:78], format: "2024-12-16 18:10:00" "2024-12-17
09:01:30" "2024-12-18 20:32:53" "2025-01-02 09:33:18" ...
 $ amount    : num [1:78] 9.3372 0.0481 0.1232 -0.065 0.9656 ...
 $ price     : num [1:78] 107012 107359 101423 96408 96606 ... 



I am afraid I must learn to use traceback() as I can't see any obvious
reasons for the error.
