使用带插入包的自定义方法的正确语法

Question

我使用第46页的程序包插图（pdf）中记录的自定义方法语法在插入符trainControl()中收到以下错误。是否有人知道此文档是否过期或不正确？它似乎与不使用“自定义”参数的插入符documentation page不一致。

> fitControl <- trainControl(custom=list(parameters=lpgrnn$grid, model=lpgrnn$fit, 
                                         prediction=lpgrnn$predict, probability=NULL, 
                                             sort=lpgrnn$sort, method="cv"), 
                             number=10)

Error in trainControl(custom = list(parameters = lpgrnn$grid, model = lpgrnn$fit, :
unused argument (custom = list(parameters = lpgrnn$grid, model = lpgrnn$fit, 
prediction = lpgrnn$predict, probability = NULL, sort = lpgrnn$sort, method = "cv", 
number = 10))

Answer 1

引用的pdf已过期。插入符号网站是文档的规范来源。
