Visualization of correlation coefficient matrix

This article will use psych In the bag pairs.panels Command to visualize the correlation coefficient matrix ：

library(psych)

The following data are r Language data comes with data

pairs.panels(attitude)

Let's take a look at the parameters of this command ：

pairs(x, smooth = TRUE, scale = FALSE, density=TRUE,ellipses=TRUE,
     digits = 2,method="pearson", pch = 20, lm=FALSE,cor=TRUE,jiggle=FALSE,factor=2, 
     hist.col="cyan",show.points=TRUE,rug=TRUE, breaks = "Sturges",cex.cor=1,wt=NULL,
     smoother=FALSE,stars=FALSE,ci=FALSE,alpha=.05, ...)

• x Is the data ,smooth=T Represents adding a smooth curve ,scale=T Represents the standardization of data ,density=T Is to draw the density curve
•
