...write classes, using S3 ou S4 models. And it seems that S4 is the best model, so I thing I should use this one. I´m new user of R and I´m searched on the net some information about creating new classes. I found this document: http://www.biostat.harvard.edu/courses/individual/bio271/lectures/L11/S4Objects.pdf If someone knows some docs about creating our own classes, could please, post its url at here ? More one question... It seems that some documents about S can be applyed to R. How do you know if you can use this documentation using R ? I´m asking this because some stufs I was looking for I fo...

Hi R people: I would like to learn about classes, methods, S3 and S4. Which book would be the most helpful for this info, please: the green one or the white(and blue) one? Or is there something that would be even better, please? Thanks in advance. Sincerely, Laura Holt mailto: lauraholt_983 at hotmail.com R 2.1.0 Windows. trying to learn

...new function Plot.pedigree in the .GlobalEnv which mostly achieved what I wanted to. However, I'm sure that's not the tidiest way to do it. We don't have the green book, but there's lots of interesting information I found here: http://www.stat.auckland.ac.nz/S-Workshop/Gentleman/S4Objects However, there's something I'm missing in connecting that information into knowledge of how I go about making a new method or slot or whatever is sensible in this case. What does one make of this: > getClass(class(kinship:::plot.pedigree)) No Slots, prototype of class "functio...

...ear" calls standardGeneric to dispatch on a different name ("funName")! This is R-1.8.1 on RH-7.3 I came across it while trying to write a helper function that would "safely" create generics when a function with such a name already exists. Here is what I adapted from S4Objects but it doesn't work because of the above-mentioned problem. Any suggestion how to make it work, please? setMakeGenericMethod <- function(methodName, className, fun) { # sets a method and creates the generics if necessary if (!isGeneric(methodName)) { if (is.function(methodName)) {...

Dear R People: Could someone direct me to some documentation on the difference between S3 and S4 classes, please? For example, why would a person use one as opposed to another? Maybe pros and cons of each? Thanks in advance! R Version 2.2.0 (I'm downloading the new one this afternoon!) Windows. Happy New Year!
