我在R（2.13.0）中加载了paleoTS并试图使用fit3models.joint函数，但不能。我尝试重新安装，但它确保我已经存在paleoTS！帮助赞赏：
Error: could not find function "fit3models.joint"
> utils:::menuInstallPkgs()
Warning: package 'paleoTS' is in use and will not be installed
答案 0 :(得分：0)
还没有足够的信息。我发现没有证据表明fit3models.joint是paleoTS包中的函数：您的意思是fit3models ...？或fit3models(...,method='Joint')（基于查看?fit3models中的示例？
