Why is a paleoTS function not working?

I have loaded paleoTS in R (2.13.0) and tried to use the fit3models.joint function, but can't. I tried reinstallin开发者_高级运维g but it assures me paleoTS is already there! Help appreciated:

Error: could not find function "fit3models.joint"
> utils:::menuInstallPkgs()
Warning: package 'paleoTS' is in use and will not be installed

Not enough information yet. I see no evidence that fit3models.joint is a function in the paleoTS package: did you mean fit3models ... ? or fit3models(...,method='Joint') (based on the looking at the examples in ?fit3models ?
