Slots as @title and @documentation in S-Plus
You may use attributes, e.g. attr(vMatrix,"title") <- "The first time and so on." attr(vMatrix,"title") (see ?attr for details, especially for the list of "reserved" attribute names). Martin

In S-Plus, data frames have slots as @title and @documentation. It seems that R is different. After the following code: vMatrix<-sqlQuery(sqlMatrix,sqlStr1) If I want to add some memo to vMatrix??it would be vMatrix at title="The first time and so on." in S-Plus. But in R, data frame has no slots. According to help and documentations, it seems that S4 class has slot. But data frame is not S4. The S4/S3 confused me since I am new to R. I wonder whether thers's easy way to attach some memo to a data frame, as in S-Plus. Thanks.
