plot in r - remove and rename titles and labels

Question

I have created the following plot

bootresults<-boot.relimp(model3_a_out, b=1000) 
ci<-booteval.relimp(bootresults, norank=T)
plot(ci)

How can i remove the plots title and subtitle ? also how to remove the annotation of the bottom ?

i tried main = NULL but it does not work.

also how can i rename the variables ?

for reporoducible example:

> usedata('gpa')

> bootresults<-boot.relimp(gpa.model, b=1000) 
> ci<-booteval.relimp(bootresults, norank=T)
> plot(ci)

Answer 1

Main title and sub title can remove plot(x = x, y = y, main = NULL, sub = NULL) . But i think your plot is made mtext function. mtext example(using plot margin) So they recommend make another plot. mtext answer
