R - change size of axis labels for corrplot

Question

I am using the following with corrplot:

require(\"corrplot\") ## needs the corrplot package
corrplot(cor(lpp_axis1, lpp_axis2), method=c(\"number\")         


        

Answer 1

Given the examples you added, you might have to increase the dimensions of the plot and set the outer margins to accommodate the length of your labels.

The current plot dimension can be accessed with par()$pin and the outer margins with par()$omi .

You can change the plot dimension and the outer margins by adapting the following example:

require("corrplot")         ## needs the corrplot package  
data(mtcars)  
  corr <- cor(mtcars)    
par(pin=c(7,7))              ##  (width, height) in inches    
par(omi=c(0,1,1,0.5))        ## (bottom, left, top, right)  in inches  
corrplot(corr, method="number", tl.cex = 2)
