plot.xmean.ordinaly vs plot() in package "rms"
Please keep the mailing list included in the thread. I can't tell if you do understand and are just being sloppy, or if you are completely confused, because xmean.ordinaly() and plot.xmean.ordinaly() are two completely different symbols in R. As for being "safe"... you may choose to be specific or not, but plot and plot.xmean.ordinaly are both equally "safe" to call, and being too specific can cause problems sometimes as well.

Dear Jeff, Thank you so much! So if I understand the S3 object documents correctly, the xmean.ordinaly() command and plot() command are interchangeable as long as x is an object x of class "xmean.ordinaly"? So would I be right to think that I might as well just xmean.ordinaly() to be safe? Many thanks, On Sun, 17 Mar 2019 at 02:08, Jeff Newmiller <jdnewmil at dcn.davis.ca.us> wrote:
Read up on S3 object orientation[1]. If you have an object x of class "xmean.ordinaly" then writing plot(x) will end up invoking the plot.xmean.ordinaly function rather than the plot.default function in base graphics. This is broadly true
throughout R.

Would anyone be able to explain what the difference is between plot.xmean.ordinaly and plot() in the "rms" package? (for the
purposes
of testing the proportional odds assumption in ordinal models). In the package document (https://cran.r-project.org/web/packages/rms/rms.pdf) they seem both to be used interchangeably. Thank you!
