Mostly I am interested in using R for statistics.
I am also interested in being able to look at source code.
I hope to be able to write extensions.
I tried the suggestion below but was unable to access vcov.lm.
methods(vcov)
[1] vcov.Arima* vcov.glm* vcov.lm* vcov.mlm* vcov.nls*
Non-visible functions are asterisked
stats::vcov.lm
Error: 'vcov.lm' is not an exported object from 'namespace:stats'
I am currently using version 2.7.2 on XP.
Any suggestions on how to proceed next?
Thank You,

Subject: Re: [R] VCOV Source Code
Hello,
You can do
stats:::vcov.lm
to see the source code for that particular method. In order to see which
are the methods supported by vcov, write
methods("vcov")
Best regards,

Dear R Help,
I wonder the way to show the source code of [vcov] command. Usually, it
can show the source code after input the command and enter. But for
[vcov], it shows
function (object, ...)
UseMethod("vcov")
<environment: namespace:stats>
I appreciate for your help. Best wishes.
Christina
