I did have a verbose description of why but rather then make everyone's eyes bleed with useless details I ask the following :) To make a long story short: How can I make newmcReg[[i]]["PreIO308"] go away in the following list... er vector... no wait array.... dataframe.... awww crap... summary(newmcReg[[i]]) UNITBUILD UNITDB ITBUILD ITDB Mode :logical

Hi all, Came across this curious behavior in: R version 2.5.0 Patched (2007-06-05 r41831) A simplified example is: > all(c(NA, NA, NA) > NA, na.rm = TRUE) [1] TRUE Is this expected by definition? If one reduces this to individual comparisons, such as : > NA > NA [1] NA > all(NA > NA) [1] NA > all(NA > NA, na.rm = TRUE) [1] TRUE the initial comparison on the 3

Hello all, So I am having a puzzling problem. I am working with a 534 x 1065 data frame entitled LocalMaxExpBlue.COR which is completely full of logical values "TRUE" and "FALSE." However, when I attempt to manipulate this data frame, R does not recognize it as logical. Strangely enough, it will identify individual columns (but not rows) as logical. It will also

Greetings- Using R 1.2.2 under linux, I get the following: > l.agg<-xtabs(cbind(r.logic.interests, r.logic.morality, + r.logic.enlightened, r.logic.capacity, r.logic.mediate) + ~ grouptype, + data=gt) Error in parse(file, n, text, prompt) : parse error I know the data are structured fine, as I can use all the elements in individual xtabs()

Hi, I am trying to find an efficient way of applying a linear regression model to different factor combinations in a data frame. I want to obtain the output with minimal or no use of loops if possible. Please let me know if this query is unclear. Thanks, Murtaza

Hi All, I am in the midst of developing a library for easily recording multi-track audio for a court recording system. Well, it can be used for anything, but this is its first intended use. The idea is to simultaneously capture/compress/archive 8 to 16 mono sources (microphones) in an Ogg container using Vorbis. Then later, be able to play back only selected logical streams, or

A friend bring and Ipod, initially it didn't start because of charge, so I connected to my PC to give some charge, after that my linux didn't mount it, and when I start the iPod it shows me a folder with a sign, and that's all, nothing else matters. when I connected the iPod to the PC it start to charge and suddenly stops and shows the folder I have talked before I run the command

Hello, According to ?as.logical: "as.logical attempts to coerce its argument to be of logical type. For factors, this uses the levels (labels)." However, > as.logical(factor(c("FALSE", "TRUE"))) [1] TRUE TRUE Shouldn't it be the same as: > as.logical(levels(factor(c("FALSE", "TRUE")))) [1] FALSE TRUE according to the

Hi In V&R the "polynomial" class is explicitly specified to have no logical operators: setMethod("Logic", signature(e1="polynomial"), function(e1,e2){stop ("...")}) I too have a class of objects for which I want to specify that Logic operators do not work, but executing setClass("brob", representation = representation

This is an example from https://stat.ethz.ch/pipermail/r-help/2007-May/132573.html . With R 2.7.2: > a <- c(1, 1, 2, 2, NA, 3); b <- c(2, 1, 1, 1, 1, 1) > table(a, b, exclude = NULL) b a 1 2 1 1 1 2 2 0 3 1 0 <NA> 1 0 With R 3.3.1: > a <- c(1, 1, 2, 2, NA, 3); b <- c(2, 1, 1, 1, 1, 1) > table(a, b, exclude = NULL) b a 1 2

Not sure if this is the right place to come to, but I don't have "RHN" support.....I'm hoping someone can help me out here. I have downloaded the RHEL .ios file and burned it to DVD/CD, my laptop is primed to Boot From CD/ROM Drive, I start the installation using the semi-graphical interface, and the first few options are a breeze, then it gets to identifying the CD drive

I am using htmlParse from XML library on a paricular website. Sometimes code fails, sometimes it works, most of the time id doesn't and i cannot see why. The file i am trying to parse is  http://www.londonstockexchange.com/exchange/prices-and-markets/international-markets/indices/home/sp-500.html?page=0 Sometimes the following code works n<-readHTMLTable(htmlParse(url)) But most of the

Dear R-help, I was bitten by the behavior of all() when given logical(0): It is TRUE! (And any(logical(0)) is FALSE.) Wouldn't it be better to return logical(0) in both cases? The problem surfaced because some un-named individual called randomForest(x, y, xtest, ytest,...), and gave y as a two-level factor, but ytest as just numeric vector. I thought I check for that in my code by testing

In current virt-resize, only primary partitions(including extended partition) are supported. They are collected in an array for resize operations. Logical partitions are not supported. This series add support for resizing logical partitions. v4: rebase on upstream. v3: 1) rewrite partitions/logical_partitions/extended_partition section by the comments from Rich and Pino. 2) in 03/11

Dear all, How can I obtain the union of a list of logical values? Consider the following: x <- head(iris) x[,c(2,4)] <- NA x[c(2,4),] <- NA # > x # Sepal.Length Sepal.Width Petal.Length Petal.Width Species # 1 5.1 NA 1.4 NA setosa # 2 NA NA NA NA <NA> # 3 4.7 NA 1.3

Dear list, this is not a problem report -- I would like to ask for advise what the recommended and safe way to perform the following is or what problems might arise in doing it differently. The question is: What is the recommended way of providing a default value in a prototype statement for a derived class for a slot provided from a parent class? I have first consulted the methods package

Full_Name: Roland Puntaier Version: 1.8.1 OS: Windows XP Submission from: (NULL) (62.99.238.78) I have a data frame with some columns being logical. I wanted to calculate a column that is an AND combination of the other logical columns. I tried to use apply(df,1,all) It did not work because of the implicit string conversion. So I made the functions All<-function(...)
