...the class to value, and return the modified object. This is > NOT a primitive assignment operator , because there is no code in R > that changes type in place. See the definition of "class<-" in > the methods package for the use of this code. */ I came upon "RemoveClass()" in R/src/main/object.c which says it is __unused__ but seems to do what I would like it to do. So I tried a S4 method dispatch mechanism, but it is 3 times *slower* than unclass, and it seems to be due to the switch() statement inside getDataPart() (in R/src/library/methods/R/RClassUtil...

...if he/she experiences similar problems: The thing is that when I alter the definition of a Reference Class in a running R session and source the respective file containing the class def, sometimes the changes are reflected and sometimes not. I also tried to explicitly remove the class via 'removeClass()', and that too works at times and then again it doesn't. If it doesn't work it means that I have to shut down the session and start a new one, which is quite bothersome. I thought that it maybe had something to do with whether an explicit 'initialize' method has been defin...

'?removeClass' shows that 'removeClass' is from package 'package:methods'. Is there a command which can show me all the functions and the classed defined in a package such as 'package:methods'?

Hi all. I'm reading in a flat, comma-delimited flat file using read.csv. It works marvelously for the most part. I am using the colClasses argument to, basically, create numeric, factor and character classes for the columns I'm reading in. However, a couple of the fields in the file are date fields. I'm fully aware that POSIXct can be used as a class, however the field must obey,
