correlation - How to have diagonal labels in R Corrgram?

Question

Corrgram docs have been misleading, since 2012, as discussed in the email thread how to change variable names in corrgram diagonal about putting labels on the diagonal. Many users think wrongly that diag.panel=... is the solution but it is not as seen in the following, but I cannot use labels because it is still not yet documented

yes, the argument "labels" it's working fine!

It would be great if the docs will be be updated also with this already implemented feature

Code

library("corrgram")

ages <- seq(1,18)

corrgram(baseball,
  diag.labels=ages)

Output

There were 50 or more warnings (use warnings() to see the first 50)

R: 3.3.1
OS: Debian 8.5

Answer 1

corrgram(baseball,
  labels=ages)

Output
