Corrplot output 格式

Question

I am currently trying to fix the visual output of a generated Corrplot but have so far been unsuccessful with two things:

1. The title always gets chopped off the top

2. I can't change the color of the labels from red to black

   A <- seq(1, 100, by=1) B <- sample(A,100, replace =T) C <- sample(A,100, replace =T) D <- sample(A,100, replace =T) E <- sample(A,100, replace =T) sample(A,100, replace =T) X <- data.frame(A,B,C,D,E) X <- cor(X, method = c("spearman")) corrplot(X, method = "circle", type = "upper", diag = F, addCoef.col=T, title = "Testing")

Additionally, is it possible to just keep the first 2 variables (ie A and B) and show the correlation horizontal with every other parameter CE? Thanks for the pointers!

Answer 1

To keep the title from being truncated, use the mar parameter.
To adjust the color of the labels, use the tl.col parameter.
To have a horizontal display that only shows (A,B) by (C,D,E), get rid of type="upper" and diag=F ,
add is.corr=F and then just use the part of the matrix that you want X[1:2,3:5] .

Putting that all together, we get

corrplot(X[1:2,3:5],
 is.corr=FALSE,
 method = "circle",
 addCoef.col=T,
 mar=c(0,0,5,0),
 tl.col = "black",
 title = "Testing")
