如何更改R中PerformanceAnalytics库中chart.Correlation的颜色？

Question

I have an all numerical data frame in R (no factors or levels) for which I'm trying to plot the correlation plot with the function chart.Correlation from PerformanceAnalytics library. Documentation here

The default colors are black and red. I want to be able to change the colors primarily and other attributes if possible.

The docs say that the function takes "any other passthru parameters into pairs." I do not understand this statement. I tried to pass some of the same parameters such as bg="lightblue" but absolutely no change.

Any help would be very much appreciate it.

Update!

For what is worth - I was able to get some of the things wanted with another library which is built on top of pairs . Here is the code:

library("psych")

pairs.panels(plot_data, 
             hist.col="#00FA9A", 
             show.points=TRUE, 
             stars=TRUE, 
             gap=0.05, 
             pch=".", 
             ellipses=FALSE, 
             scale=FALSE,
             jiggle=TRUE,
             factor=2,
             main="Correlation", 
             col="#ADFF2F", 
             pty="m", 
             font=2)

I still do not know how to change the color of the data points - so there is your chance to get the points.

要更改pairs.panels 函数（心理）中数据点的颜色，请查看帮助菜单中的示例：

pairs.panels(iris[1:4],bg=c("red","yellow","blue")[iris$Species], pch=21+as.numeric(iris$Species),main="Fisher Iris data by Species",hist.col="red")
