Hi, Loading the "methods" package into R seems to change the class of a character vector from NULL to "character": > class("abcd") NULL > library("methods") > class("abcd") [1] "character" This can lead to problems. For example the "as.string" function in the "xtable" package assumes that the class of a

Hello, im trying to wrap a fairly ugly legacy schema using AR. How to handle normalized informations which aren''t connected via the pk? create table what ( myid int, myclass int, ;; references blahclass.blahid mygender int ) create table blahclass ( blahid int, mdesc1 text, fdesc1 text) ) I would like to wrap this as class What < AR::Base has_one :blahclass class

I noticed this oddity about R profiling and setMethod. First, I "test out" Rprof. > require(methods) Loading required package: methods [1] TRUE > > Rprof("test.out") > data.frame("a") X.a. 1 a > Rprof(NULL) So far, so good. Next, I define myClass. > setClass("myClass", representation(mySlot = "numeric")) [1]

Dear All, In R 3.6.3 (and earlier), method dispatch used to work for methods stored in local environments that are attached to the search path. For example: myfun <- function(y) { out <- list(y=y) class(out) <- "myclass" return(out) } print.myclass <- function(x, ...) print(formatC(x$y, format="f", digits=5)) myfun(1:4) # prints: [1]

Hi! I have implemented class specific behaviour of "[[<-.myclass"<-function(). How it is posible to call the "[[.default" on an object of myclass? Eryk Dipl. bio-chem.

Following my previous post on S3 method despatch, I put debug messages in the code of Axis, Axis.default and plot.default in graphics/R/axis.R and graphics/R/plot.R to print the class of x, at and y on plot. After recompiling R, what I see is that x *lost* its class attribute (at least for classes not known to 'graphics') in Axis, called directly from plot.default and this could be the

A general goal for the next version of R is to make S4 and S3 play better together. As mentioned in a previous thread, one limitation has been that S3 generic functions, specifically the UseMethod() call, did not make use of S4 inheritance when dispatching on general S4 objects. This has been fixed in a version committed today (updated to rev 52267). The code change is not large, but it

Hi, I'm having some problem with llvm-mc on a program after applying a pass: ../../../build/Release+Asserts/bin/clang -emit-llvm -c -I./testprof/ -I./src/headers/ -I../libtommath-0.42.0/ -Wall -Wsign-compare -W -Wshadow -Wno-unused-parameter -DLTC_SOURCE -O0 -DLTC_NO_ASM -DUSE_LTM -DLTM_DESC -o src/pk/asn1/der/sequence/der_encode_sequence_ex.bc

To maintain my R site, I'm trying to install html help files only, but also keep track of the version (with DESCRIPTION). I have the following bash script, which works except for 00Index.html. That is not a huge problem because the help files are still searchable, but I'd like to fix it. A long time ago I asked the same question, and Brian Ripley said to use --index as an option to

Something is adding a bogus comment string. Specifically " # %case^M18 ", where "^M" is a single ctrl-M character. The ^M is seen by the asm parser as an end-of-line, so the '18' is a new token at the start of a line, not part of the comment. Is your pass perhaps using label names which might include literal "^M" characters? -Jim On Jun 13, 2012, at

Hi, i tried to find the answer but didn't so my apologies if the question is obvious ! I'm trying to parallelize the following R code : pk2test = c(1:16,(12*16+1):(12*16+16),(16*16+1):(16*16+16),(20*16+1):(20*16+16)) score.mat = matrix(nc=16*4,nr=16*4) for(i in 1:(16*4)) { for(j in i:(16*4)) { score.mat[i,j] = score.mat[j,i] =

Hi section 6.1 of R-exts suggests that a package can take over a function in the base package and make it generic. I want to do this with Re() and have the following lines in my R code: "Re" <- function(x){UseMethod("Re" )} "Re.default" <- get("Re" ,pos=NULL,mode="function") "Re.octonion" <- function(x){give.comp(x,1)}

Dear R-users, I learned today that there exists an interesting topic in numerical analysis names "best polynomial approximation" (BSA). Given a function f the BSA of degree k, say pk, is the polynomial such that pk=arginf sup(|f-pk|) Although given some regularity condition of f, pk is unique, pk IS NOT calculated with least square. A quick google tour show a rich field of research

I love using ActiveRecord Migrations to build tables. Sometimes, I don''t want to use autogenerated PK''s - I want to set them automatically (why? I''m importing read only data from a large list of medications, and want to use the PK''s assigned by the medication research company...). Is there anyway to do this using Migrations? I know that I don''t

Hi all, I have two tables: TABLE 1 A pk - fk (referencesc TABLE 2) B pk C pk D pk E F TABLE 2 A pk G H I L I don''t use incremental field (id). I''d like don''t use find_by_sql. How can I define both models to use correctly find method (with include)? With only one column primary key I haven''t problems. I thought two solutions, but I don''t like these
