R help - Apr 2023 - Help with bootstrap sampling with rms package in R

Hi all,

I appreciate any help that can be offered and don?t mind sending a fee to anyone
that can help.

I am a physician and am writing a paper to be submitted to a medical journal and
am performing bootstrap internal validation by the Harrell method using the R
package called rms. It?s a multi variable logistic regression model. I have done
the 1000 sample bootstrap and generated Dxy which I have converted to AUC. But I
also want to illustrate with a histogram of all the 1000 AUC values generated
from the training AUC from each bootstrap model.

Reaching out for help with this, thanks in advance. 

Best,

Munveer
