[R] deparse, substitute and S4 generics

Hello everyone, I encountered the following confusing behavior of 'deparse' and 'substitute' while programming with S4 classes (see example below). It seems like the presence of '...' argument in the definition of the generic generates the problem. I have no clue why, can anyone explain that to me

[R] Adding a table to a lattice plot

Re: [R] deparse, substitute and S4 generics

Try putting a ... argument in the method for g as well setGeneric("g", function(object, ...) standardGeneric("g")) setMethod("g", "ANY", function(object, ...) ### change { nam <- deparse(substitute(object)) cat("name:", nam, "\n") object } ) Now it works. Bill Venables CSIRO Labo

Hello Bill, Thanks! Indeed that works. Can you give me a hunch why? Does it have anything to do with environments and scope? ~michal Bill.Venables wrote: > > Try putting a ... argument in the method for g as well > > setGeneric("g", function(object, ...) standardGeneric("g")) > > setMethod

Re: [R] recoding one variable into another - but differently for different cases

No one else mentioned this, but if those 99s represent missings, you should be using NA not a special numeric value. Hadley On Jan 22, 2008 5:40 PM, Dimitri Liakhovitski <[EMAIL PROTECTED]> wrote: > Thanks a lot, everyone! > Dimitri > > > On 1/22/08, Gabor Grothendieck <[EMAIL PROTECTED]> wrote:

[R] How to do more advanced cross tabulation in R?

Hi, I am trying to reproduce some functionalities of Excel pivot table in R, sadly, I couldn't figure out how to do it. I am wondering if this is even possible in R. Does anyone know? Here is an example: year=rep(2003,16) quarter=rep(1:4,each=4) sales=1:16 company=rep(c("a","b","c","d"),4) df=da

Re: [R] deparse, substitute and S4 generics

Michal -- setMethod creates a nested function named .local when method arguments do not match generic arguments. This changes the environment in which deparse(substitute()) evaluates, and probably is a significant warning flag about using these types of idioms with S4. Creating .local is meant I

Re: [R] How to do more advanced cross tabulation in R?

I think you are looking for ftable: xt <- xtabs(sales ~ company + year + quarter, data = DF) ftable(quarter ~ year + company, xt) You also might want to look at the reshape package and the rpad package. Here is a demo of a pivot table in R using rpad for the user interface and reshape for the da

Re: [R] recoding one variable into another - but differently for different cases

Note that if you do use NA rather than 99 as others have suggested then the A==4 term should use ifelse rather than multiplication since 0 * NA = NA, not 0: transform(Data, new = (A == 1) * ((B == 1) - (B == 2)) + (A == 2) * ((B == 2) - (B ==1)) + ifelse(A == 4, NA, 0)) In fact, although more

Re: [R] a Q about R in unix

I would suggest that you view unix and linux as being essentially the same, from the point of view of using R. I use ESS for syntax coloring, help with indentation and parentheses matching, that sort of thing, and it works very well. -Don At 11:08 AM -0500 1/22/08, Wensui Liu wrote: >Dear All,
