With quantmod 0.4.28 and R 4.5.2, and ESS (but on GNU/Linux),
I can change colours, e. g.
library("quantmod")
getSymbols("AAPL")
chartSeries(
AAPL,
type = "candlestick",
subset = '2025-07::2026-01',
theme = chartTheme("black",
up.col = "blue"))
gives me "blue" up-bars. The same example also works
when I run it from a terminal.
Could this be some Apple-specific thing?
