Dear List, I have the code below, where I am using the constrained optimisation package, 'constrOptim.nl' to find the values of two values, b0 and b1. I have no problems when I enter further variable information DIRECTLY into the functions, fn, and heq. In this instance I require fn to have -0.0075 appended to it, and in the case of heq, h[1] has -0.2. library(alabama)

Good morning R list, My apologies if this has *already* answered elsewhere, but I have not found the answer that I am looking for. I have a character string, i.e. form<-c('~ A + B + C + C / D + E + E / F + G + H + I + J + K + L * M') Now, my aim is to find the position of all those instances of '*' and to remove said '*'. However, I would also like to remove the

Dear R users, I have a problem. I would like to solve the following: I have pL = 1/(1+e^(-b0+b1)) pM = 1/(1+e^(-b0)) pH = 1/(1+e^(-b0-b1)) My target function is TF= mean(pL,pM,pH) which must equal 0.5% My non-linear constraint is nl.Const = 1-(pM/pH), which must equal 20%, and would like the values of both b0 and b1 where these conditions are met. I have searched widely for an answer,

Dear List, I am using constrOptim to solve the following fr1 <- function(x) { b0 <- x[1] b1 <- x[2] ((1/(1+exp(-b0+b1))+(1/(1+exp(-b0)))+(1/(1+exp(-b0-b1)))))/3 } As you can see, my objective function is ((1/(1+exp(-b0+b1))+(1/(1+exp(-b0)))+(1/(1+exp(-b0-b1)))))/3 and I would like to solve for both b0 and b1. If I were to use optim then I would derive the gradient of the

Hi R experts I am just wondering if something is already available (or easily adaptable) to do the following. I am planning to build linear models for all possible combinations of terms, so for example if the terms are sent into a function as this string " X1 + X2 + X3 + X4 + X1:X2" I would want to build models for all possible combinations of these 5 terms, e.g. m1 <- lm( y ~

Hi all A couple of questions about string processing from someone who has only scratched the surface so far. 1) I am wanting to send some strings into a function to allow flexibility inside. My first idea has been e.g. auto_io <- function( var_string, factors ) { # e.g. var_string sent as "test_file.txt" factors sent as "x1 + x2 + x3" # input data_name <- get(

I understand this isn't a r specific question. I'm switching departments to work with the analytics team at my company as a "service" side manager to better incorporate the analytics process into product design / production. We're an online gaming company. As I'm going through tools like R, rapidminer, tableau, I was also thinking that I should get some formal training

Hi, I am a newbie of R, and playing with the "ifelse" statement. I have the following codes: ## first, for(i in 1:3) { for(j in 2:4) { cor.temp <- cor(iris.allnum[,i], iris.allnum[,j]) if(i==1 & j==2) corr.iris <- cor.temp else corr.iris <- c(corr.iris, cor.temp) } } this code is working fine. I also tried to perform the same thing in another way with "ifelse":

Hi all. I just got openssh 2.5.1p1 and when I installed it, it's man pages doesn't seem to be formatted right. I'm on Solaris 8. Here is how it looks: man ssh Reformatting page.

It is intended to replace rlogin and rsh, and provide secure encrypted

Hello, I am not sure where to begin with this problem or what to search for in r-help. I just don't know what to call this. If I have 5 columns, the first 2 are the x,y, locations and the last three are variables about those locations. x<-seq(1860,1950,by=10) y<-seq(-290,-200,by=10) ANN<-c(3,0,0,0,1,0,1,1,0,0) CTA<-c(0,1,0,0,0,0,1,0,0,2) GLM<-c(0,0,2,0,0,0,0,1,0,0)

Hi, I want to do a barplot with no black lines drawn around each bar and no space between each bar. I can do the nospace bit but keep getting black line around each bar no matter what I try. Ie. for a red bar I want a red border, for a yellow bar a yellow border and so on. I've tried everything I can think of but no luck. Any suggestions? At the moment I'm using R 5.1 under Redhat Linux

hi, I have 2 files example 1 and example 2 and would like to know what is in example2 and not in example1 (attached) V1 contain data which could be in duplicated which I am using as identifiers I used setdiff(example2$V1,example1$V1) to find the identifiers which are specific to example2: [1] "rs2276598" "rs17253672" I am looking for a way to get an output with all

Hi R people I am using regsubsets() to fit large numbers of models and collect summary statistics in order to perform a Bayesian analysis of multi-way ANOVA with specific prior information. In general the variables have differing numbers of levels >=2. This works well but with variable of more than 2 levels there are naturally some arbitrary decisions about which treatment contrasts to

The attached patch (relative to the current CVS snapshot) uses a perl script to convert the OpenSSH manpages from the BSD -mdoc format to the -man format used by other systems. This allows the unformatted manpages to be installed normally, rather than defaulting to preformatted pages. I'd like to see this patch integrated into the portable version of OpenSSH. Please let me know what you

Hi all. I've been reading through Wi-Ki and at the extensions.conf file description (http://www.voip-info.org/wiki-Asterisk+config+extensions.conf) The author says this: "One day, someone is going to write a proper scripting language for Asterisk that can understand a simpler, easier (and more traditional) scripting syntax. All it would need to do is translate the "high

I just upgraded a box to 1.2.3 this morning after encountering the issues noted earlier on the list. Everything is great. In fact, a LOT better. In the past few weeks, I've been battling with BV to address dropped outgoing voice packets (the flipside is that I haven't experienced this with other providers during tests), and an annoying mechnical 'chirp' at the start of a call.
