Maybe this is not directly related to R, but I appreciate you can help me with an idea. I use the following ggscatter function to plot a Pearson correlation Coefficient and it works fine. In the chart I see both R-value and P-value.
ggscatter(mydata, x = "V1", y = "V2", add = "reg.line", conf.int = TRUE, cor.coef = TRUE, cor.method = "pearson")
On the other hand, when I use this command
res <- cor.test(mydata$V1, mydata$V2, method = "pearson")
The R and P values are different from ggscatter.
I would like to know:
1- Why they are different?
2- How to print P and R values of ggscatter on terminal?
