问题描述
我正在尝试使用 theme
参数更改条形的颜色,但出现错误:
I am trying to change the colours of the bars using the theme
argument, but I get an error:
library(quantmod)
getSymbols("SPY", from=Sys.Date()-500, to=Sys.Date())
chart_Series(SPY)
chart_Series(SPY,theme=chart_theme(dn.col = "cyan"))
# Error in chart_theme(dn.col = "cyan") : unused argument (dn.col = "cyan")
推荐答案
看代码.chart_theme
没有参数,所以尝试 chart_theme(dn.col="cyan")
没有意义.
Look at the code. chart_theme
takes no arguments, so trying chart_theme(dn.col="cyan")
makes no sense.
> args(chart_theme)
function ()
NULL
chart_theme()
返回一个列表,您想修改其中的一部分,所以就这样做.
chart_theme()
returns a list and you want to modify portions of it, so just do that.
myTheme <- chart_theme()
myTheme$col$dn.col <- "cyan"
chart_Series(SPY,theme=myTheme)
