...e names: FOLSTAT, GENDER, ASBIN; all three were categorical variables, FOLSTAT denoted follow up status for the subjects and had seven levels, GENDER denoted sex (two levels: male,female), and ASBIN denoted binarized arsenic concentrations (two levels: "<0.05", ">0.05" denoting less than 0.05 mg/L and more than 0.05 mg/L respectively). To illustrate, I used the following code for crosstabulation: x <- table(FOLSTAT,GENDER,ASBIN) # from the results, I then wanted to subset a table for the ASBIN value ">0.05" I used the following code to subset the t...

Dear list, I'm trying to fit a chapman-richards equation to my data, only I cannot interpret the parameters a, b and d. I know that the parameter b denotes the asymptote, but for the others I couldn't figure out. But I do need to know this in order to set my starting values. Here's the model: modPoplar<- nls(Diameter ~ d*(1-exp(-b *Age))^a ,start=list(a=20,b=0.9,d=33)) I attached

I'm working on some heatmaps, and the person I'm working with would prefer a red-black-green color palette (red denoting gene induction and green denoting gene repression). Does such a palette exist already? If not, is there an easy way to create one? Thanks, Jake

Please give me some help, many thanks. I graphed a expected CDF line of a binomial distribution on a graph, And I have some observed points (observed CDF) from 4 groups fall on the smooth CDF line. I cannot really get the legend I want legend ('topleft', c('a, 'b', 'c', 'd', 'expected CDF'), col=c(1,2,3,4), pch=c(0,1,2, 3, '' ),

I'm trying to rekey values which denote there is no values, i.e., '-999' in a dataset which contains both '-999' and NA entries. When I try the following command I get the following error: > data.frame[data.frame$MAR <= -99999,"MAR"] <- NA "missing values are not allowed in subscripted assignments of data frames" Example of data: YEAR JAN

Hi all, Recently I have implemented a transformation pass based on LLVM3.5 and its function is to duplicate the function's argument list in a bytecode file and replace all use of original function with modified function. In LLVM3.5, the pass can work properly. However, when I tried to transplant the pass to LLVM3.9, the error "Argument value does not match function argument type!"

Hi all. It's been a long time since I wrote to this list. Glad to see the R project well and working. I am working with a 3D plot similar to this: http://old.nabble.com/file/p26525177/rgl-device.png rgl-device.png The underlying picture is a JPEG image, loaded with the rimage package and coerced to the matrix. Spheres denote control points, collected from this picture and must be

As an inveterate user of vi, I was pleased to stumble on how to use it for editing R commands. When an interactive R session is launched under unix, the command line editor most likely defaults to emacs. Typing <esc>,<ctrl>+j will switch this to vi editing mode (see below for possible exceptions). excerpted from readline(3) manpage: vi-editing-mode (M-C-j) When in emacs

...mbers, I need some help about programming in S language. My problem is as follows: I have meteorological data (about rainfall measurement each day from 1989-2002), say like http://www.angelfire.com/ab5/get5/data.rainfall.txt or http://www.angelfire.com/ab5/get5/R.rainfall.txt in a sequence of 0(denoting dry day)'s and 1(denoting wet day)'s. I want to construct a frequency distribution table of various lengths (1,2,3,4,5,6,7,8,9,or more) of observed wet spells (number of successive 1's) and dry spells (number of successive 0's) occurring in data. How should i proceed? Is there any...

Is there code in R to automatically assign letters to different groups that are found to be statistically significant using a post-hoc test following an ANOVA? For example, let's say I found that relative rates of tree growth were statistically significant between tree species using an ANOVA and then I ran a TukeyHSD post-hoc test to determine which species were statistically

Whether restricted pointer is declared in the middle of a block or not, does not matter from the standard's perspective.

Hello All, I am facing a unique problem and am unable to find any help in R help pages or online. I will appreciate your help for the following problem: I have 2 data-frames, samples below and there is an expected output R Dataframe1: C1 C2 C3 C4...... CN R1 0 1 0 1 R2 1 0 1 1 R3

Dear all, I would like to model the relationship between y and x. y is binary variable, and x is a count variable which may be possion-distribution. I think it is better to divide x into intervals and change it to a factor before calling glm(y~x,data=dat,family=binomail). I try to use rpart. As y is binary, I use "class" method and get the following result. >

Hi all, After trial and error by myself for a few hours, I decide to ask for your help. I have a training set which is a matrix of size 200 x 2, where the two columns denote each independent variable. I have 200 observations. ----------------- ss=data.frame(trainingSet); result=lm(trainingClass~ss$X1+ss$X2); ----------------- where trainingClass denotes the true classes of the training data.

I have some stuck channels that I think I'm going to have to bounce Asterisk to get rid of, but am curious to know what they are and how they've managed to accumulate. The show up with a channel identifier of '(None)' as in the output below, and do not show up in the soft hangup list, and so can't be cleared by that method. Here is the output from iax2 show channels:

Assume we have a function like: foo <- function(x, y) how is it possible to define a binary indexing operator, denoted by $, so that x$y functions the same as foo(x, y)

Hi, I want to implement a new intrinsic in llvm that will denote a parallel section within a function. I followed the documentation for extending llvm (http://llvm.org/docs/ExtendingLLVM.html) but there is something about the working mechanism that is not clear for me. 1. Why do we have to add support for the C backend? Is this only necessary to transform the llvm assembly (bytecode) into C code
