Corrplot output format

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 (i.e A and B) and show the correlation horizontal with every other parameter C-E? Thanks for the pointers!

im not sure what the last bit means. I can't picture it. For the colour, add tl.col = 'black' and for the title one hacky way is to use title = "\nTesting" - morgan121

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")
