I was looking for all the glm-related 'family' functions in stats using the following predicate that returns TRUE for any function whose first argument is called "link". is.family <- function(object) is.function(object) && identical(names(as.list(object))[1], "link") It threw an error when applied to SSfol > is.family(SSfol) Error in

Dear R helpers, I have been using the loadings function from the multiv library and I get the typical output (see below). When I try to export these results to a file using a write.table() I get the following error message "Error in as.data.frame.default(x[[i]], optional = TRUE) : can't coerce loadings into a data.frame" Any idea why write.table is doing that and any

Hi everyone, Is there any reason why we should not automatically coerce a factor supplied as an argument to col in a plotting function? The following modification (to R-1.6.1) seems pretty harmless > plot.xy function (xy, type, pch = 1, lty = "solid", col = par("fg"), bg = NA, cex = 1, ...) { if (is.factor(col)) col <- codes(col)

Greetings Samba team, It has been a long time since I needed to ask a Samba technical question. Server and workstation are both running the latest Samba packages via Ubuntu 16.04 LTS. I recently applied the security updates... actually that was yesterday I applied them. > samba (2:4.3.11+dfsg-0ubuntu0.16.04.23) xenial-security; urgency=medium > > * SECURITY UPDATE: client code can

Dear R forum, I want to replace all the elements in a data frame (dd) which match the character "x" with "0". What's the most elegant way of doing this (there must be an easy way which I've missed)? I settled on the following loop: >for(i in 5:12){ # These are the column of dd I am interested in >dd[which(dd[,i]=="x"),i]<-0 >} The

Hallo! I lese gro?e Zeitreihen in R ein z.B. mit: > disc<-read.table("F:/R/DATA/discount_rate_usa.txt") disc hat dann folgende Struktur: > disc[1:5] V1 V2 1 01/03/1955 1.5 2 01/04/1955 1.5 3 01/05/1955 1.5 4 01/06/1955 1.5 5 01/07/1955 1.5 ich will das disc als Zeitreihe erkannt wird und will z.B 01/03/1955 in ein Datum verwandeln, aber es wird als

Hello everyone, I need to create and work with some big matrices that actually have somewhat over 2 million columns and 117 rows. To do some calculations on such big matrices R just needs too much memory for my PC (4GB installed). So I need a solution to work with large datasets. I'm trying to use the ff-package but I don't think I really understand the whole functionality of the

As nobody seems to answer my request, I simply post it again. Is there any reason why the r-help-mailinglist should not be converted to a newsgroup? These were the advantages of a newsgroup I mentioned earlier: -) you can easily search the archives -) the discussion is faster (I experience that the R-mailinglist has a lag of about 1 to 2 hours (not for everyone!!!). When I ask a question, I get

I'm looking for a function for the 'multiple correlation' but can not figure out what it is called in R by using the html search function. Maybe it is called in another way in english?

i don't know, whether this is a bug or it is intended: when using winedt and R together it works perfectly, as long as R is run in mdi (multiple window mode). When you switch to sdi (single window mode) winedt, sends no command at all: no history, paste, source or script. Thomas Pesl > version _ platform i386-pc-mingw32 arch x86 os Win32

Hi there - I have been trying to generate some simple stats and save the results to a file. My data looks like this: x y z exp 0 3 5 1 2 11 10 1 4 4 5 1 7 6 4 1 11 1 2 2 5 7 1 2 3 3

Perhaps someone can enlighten me here: R> x <- factor(LETTERS[1:3]) R> x [1] A B C R> mode(x) [1] "factor" R> class(x) [1] "factor" R> mode(unclass(x)) [1] "factor" S-PLUS has > x <- factor(LETTERS[1:3]) > mode(x) [1] "numeric" > class(x) [1] "factor" > mode(unclass(x)) [1] "numeric" ???

Hi all, Based upon an offlist communication this morning, I am somewhat confused (more than I usually am on most Monday mornings...) about the use of grep() with factors as the 'x' argument. The argument guidance in ?grep indicates: x, text a character vector where matches are sought. Coerced to character if possible. and in the Details section: Arguments which should be

When I read a table (the dimnames of the table are numbers), R reads the column names as: X plus the number (X1,X2,X3,...) and the rownames as the numbers (1,2,3,...) How can I suppress this action? The code and the output: ^^^^^^^^^^^^^^^^^^^^^^^^ > r2<-read.table("h:\\matrix",header=T,dec=",",na.strings="-99") > dimnames(r2) [[1]] [1] "500"

I was trying to convert a vector of POSIXct into a list of POSIXct, However, I had a problem that I wanted to share with you. Works fine with, say, numeric: > v = c(1, 2, 3) > v [1] 1 2 3 > str(v) ?num [1:3] 1 2 3 > l = as.vector(v, mode="list") > l [[1]] [1] 1 [[2]] [1] 2 [[3]] [1] 3 > str(l) List of 3 ?$ : num 1 ?$ : num 2 ?$ : num 3 If you try it with POSIXct,

I have a function that manipulates a list of numeric and character components of equal length and wants to return a data.frame. EG, f<-function() { a<-list(Int1=1:5,Char1=letters[1:5],Char2=letters[6:10]) b<-data.frame(a) } How can I get the columns Char1, Char2, (...CharN) returned coerced to character and not factor? It appears that I could coerce individual columns by

i wonder about the following examples showing incoherence in how type conversions are done in r: x = TRUE x[2] = as.raw(1) # Error in x[2] = as.raw(1) : # incompatible types (from raw to logical) in subassignment type fix it seems that there is an attempt to coerce the raw value to logical here, which fails, even though as.logical(as.raw(1)) # TRUE likewise, x[2]
