similar to: Several R vs S-Plus issues (PR#1110)

Also in assign() there some arguments lacking in R such as 'frame' and 'where', though I guess that 'frame' in S may be similar to 'pos' in R.

Hi, all, I've been converting code from S-Plus ("S" for short) to R for a few weeks. Here are some differences I've found, aside from the big well-known ones (scoping, models, data storage) and the contents of Kurt Hornik's FAQ section 3.3.3. Let me start with the ones that seem like serious bugs or deficiencies: 1) LETTERS[c(NA,2)] in S is

Hello, R-devel! I posted to R-help, and (inappropriately) to R-bugs, this R/S-Plus difference: > LETTERS[c(NA,2)] in S is c("","B"), but in R is c("NA","B") Kurt Hornik <Kurt.Hornik@ci.tuwien.ac.at> wrote: > I think we do not want to change this. ... > R> is.na(LETTERS[c(NA,2)]) [1] TRUE FALSE > so we really have NA but it is

R> myfun <- function(x, ...) {x[...] <- 0; x} R> myfun(3) Error in myfun(3) : SubAssignArgs: invalid number of arguments It fails because no ... was passed. The workaround (and desired behavior) is: R> myfun <- function(x, ...) {if (missing(...)) x[] <- 0 else x[...] <- 0; x} R> myfun(3) [1] 0 Deja vu? This is the one piece of my PR#1110 (Oct 3, 2001) that I

I often use merge with dataframes that contain character vectors which have elements that are sometimes "NA" (meaning the string NA, not the same thing, obviously, as NA in a numeric or factor vector). For example, the stock ticker for Nabisco was "NA". Unfortunately (for me), it seems like merge insists on inserting "NA" for missing values. My question: Is there some

Hi, I understand work is being done to improve read.table(), especially by Prof. Brian D. Ripley. I offer below a version that I wrote, in the hope some aspects of it may prove useful or at least inspire discussion. Be aware that my version differs in a couple fundamental ways that reflect my aversion to dataframes and factors. So it returns a list of vectors which are all character,

All, I have a package BondLab, all variables are passed to the models via Cusip objects. ? The only variables input by the user are? settlement date,? price or yield or spread. ? Further price may be passed as 100.125, 100-8 (1/8), or 100-2 (2/64) or 100-2+ (5/128).? Once passed these variables must have a steady state (in decimal). ?After reading the R documentation and Hadley's book I

Hi, here im unable to run a string handle function called unpaste(). for eg:- a<- "12345_mydata" Actually my requirement what is i need to get , only 12345. Means that , i need the all letter as a word which is before of first " _ " - symbol of "a". i tried to do with unpaste, it says function not found. After that i tried with "strsplit() ". it

Hi all, Here''s what I''ve come up with so far for a pure Ruby Dir.glob for MS Windows. It almost works. The problem right now is the [] notation, which I''m not translating properly into a regex. I haven''t started on the ''**'' notation yet either, but I figure that''s more of a control flow issue. Feel free to disagree with me and/or

Dear all, Maybe, I am doing something wrong, but using R-2.5.0 on my Intel-Mac, I have problems using function callNextMethod() in method initialize. I am loading the following code as file "testS4.R": setClass("baseClass", representation(myname = "character", mydir = "character", "VIRTUAL"),

I am using getSymbols function from quantmod package to get price data from internet. Currently I have: my.ticker <- "IBM" getSymbols(my.ticker,src="google") This creates an xts object named my.ticker which contains historical price data for IBM. How can I call and manipulating this xts object using my original string my.ticker? I want to do: colnames(my.ticker) <-

Hello, Easy ways to "unpaste"? xp <- paste(x2, x3) # x2, x3 are two non-numeric columns. ............. ......................... xfg <- data.frame(xp,sc1, sc2, sc3) # sc1,sc2, sc3 are numeric cols. I want xp to be split up to form a new dataframe of the form (x3, sc1, sc2, sc3). IMPORTANT info : elements of xp have the form abc<space>efg, with abc in x2 and efg in

Since I am using dovecot I do not have courier installed, but Courier had a very handy tool for making maildir folders called `maildirmake` which I used in some automated backup scripts. How do I duplicate maildirmake in dovecot? for example: #!/bin/bash # v1.2a Testing for new dovecot install # Archive mail from folders without [0-9]{4} Maildirs # after they are 21 days old to a yearly folder

Hi, I believe this is kind of a long standing bug though. In R-3.0.1, but this also happened in previous versions, the long version '--outdir' is not recognised: For `R CMD check --outdir=mydir pkg_0.1.tar.gz` we get: Warning: unknown option ‘--outdir=mydir’ But with `R CMD check -o mydir pkg_0.1.tar.gz` we get: * using log directory ‘/home/renaud/Documents/projects/mydir/pkg.Rcheck’

Hello! I want to detect some environment on a remote host (in C program, getenv()), but it is failed.

Hi, I do not understand why after I called apply on a function that returns an xts (getIdvAdjSeries) it returns a matrix whose columns are just numeric value of time series in xts instead of a list of xts objects. Basically, I called the following: apply(matrix(tickers,ncol=1),1,FUN=getDivAdjSeries) getDivAdjSeries <- function(ticker) { seriesName <-
