Hi all,

happy new year.

I am exploring the confint function in R and the oppotunities for multiplicity adjustment.
In fact, the confint function allows an adjust argument :

In my current models I can apply adjust= e.g. "bonferroni", "none", "sidak", "mvt" and "tukey" (which is the default).

I cannot, however, find any documentation which tells me what the options really are; the ones above are only the options I found by googling, and finding pages like this one.
??adjust gets me nowhere in practice.

I emphasize that adjust under confint is not the same as p.adjust which is documented here, but naïvely I thought the arguments would be the same.
If I specify adjust="holm" or adjust="hochberg" it defaults to Bonferroni in models I am looking at, so either these methods are not implemented for confint or they achieve the same in my models, not sure. If I do adjust="eat.my.shorts" etc then I don't get an error but just bonferroni :-)

Note that the adjust argument is one of the "..."'s so isn't part of the function documentation. It must be mapped out somewhere???

So... Can anyone point me to some online documentation which tells which options the adjust argument allows? Or can any tell me how how I could systematically look up this type of question generally?

I could be wrong, but...
Best regards,
ElMaestro
