similar to: Bi variate minimization problem

------------------- Version 2 of my problem improving the definition of what the optimal solution would be. Dear all, I'm working on the following problem: Assume two datasets: Y, Y that represent the same physical quantity Q. Dataset X contains values of Q after an event A while dataset Y contains values of Q after an event B. In R X, Y are vectors of the same length, containing

Hi Petr and thanks for your reply, That's the problem I don't want to modify the labels of my legends but the title of the legend in itself inserting my custom text :) Take for example the 1st graph in this tutorial http://www.sthda.com/english/wiki/ggpubr-r-package-ggplot2-based-publication-ready-plots I want to change the "sex" in "sex subscript 2" or "

Hi There are plenty of examples https://stackoverflow.com/questions/6202667/how-to-use-subscripts-in-ggplot2-legends-r https://stackoverflow.com/questions/19507742/using-expressionpaste-to-insert-math-notation-into-a-ggplot-legend which you can modify. If you say "but it wont' seem to work" how can we know what does it mean? Plotmath expressions are rather tricky, especially if

Hello, I'm trying to fminimize the following problem: You have a data frame with 2 columns. data.input= data.frame(state1 = (1:500), state2 = (201:700) ) with data that partially overlap in terms of values. I want to minimize the assessment error of each state by using this function: err.th.scalar <- function(threshold, data){ state1 <- data$state1 state2 <- data$state2

Hi all, ok I have this issue: I want to change my graphs legends to custom text, often requiring the use of superscripts/subscripts I tried to use this instruction I found on stack overflow: labs(x = "R(Ohm)", y= "CDF", aesthetic= " Content (%)" ) but it wont' seem to work. Also tried bquote for super/ subscripts xlab(bquote(~x~/(~x~ + ~MO[2]~)*

Dear all, I would like to generate bi-variate normal data given that the first column of the data is known. for example: I first generate a set of data using the command, x <- rmvnorm(10, c(0, 0), matrix(c(1, 0, 0, 1), 2)) then I would like to sum up the two columns of x: x.sum <- apply(x, 1, sum) now with x.sum I would like to generate another column of data, say y, that makes

I am running my code in a loop and it does not work but when I run it outside the loop I get the values I want. n <- 1000; # Sample size fitglm <- function(sigma,tau){ x <- rnorm(n,0,sigma) intercept <- 0 beta <- 0 ystar <- intercept+beta*x z <- rbinom(n,1,plogis(ystar)) xerr <- x + rnorm(n,0,tau) model<-glm(z ~ xerr, family=binomial(logit))

Updating gnulib has caused -Wformat-signedness to be enabled. This has revealed many problems in C format strings. The fixes here fall into the following main categories: - Using %d with an unsigned parameter. - %x and %o expect an unsigned argument. - uid_t and gid_t are unsigned on Linux. The safe way to print these is to cast them to uintmax_t and then print then using the %ju

I am new to R and I am trying to do a monte carlo simulation where I generate data and interject error then test various cut points; however, my output was garbage (at x equal zero, I did not get .50) I am basically testing the performance of classifiers. Here is the code: n <- 1000; # Sample size fitglm <- function(sigma,tau){ x <- rnorm(n,0,sigma) intercept <- 0 beta

library(ROCR) n <- 1000 fitglm <- function(iteration,intercept,sigma,tau,beta){ x <- rnorm(n,0,sigma) ystar <- intercept+beta*x z <- rbinom(n,1,plogis(ystar)) xerr <- x + rnorm(n,0,tau) model<-glm(z ~ xerr, family=binomial(logit)) *int*<-coef(model)[1] *slope*<-coef(model)[2] # when add error you are suppose to get slightly bias slope. However when I change

hello respected ppl... am a engg. student...i was trying to use R in statistical calculations now the problem is..i imported a huge tsv file onto R...it has a column which gives cost...and it has "$" with each numerical value in this column...it is something like this..$.05,$.1,$.075...and so on.. R is reading it as "character vector"... i tried using all the arguments but

Dear useRs, my question could be very basic for which i apologize in advance. Each column of a matrix with dimensions 365 rows and 37 columns was drawn against another matrix of dimensions 365 rows and 1 column. with that i was able to draw 37 curves on the same axis. now i want to draw an average curve of these 37 curves on the same axis in such a way that all the curves (average and 37
