hi, I am encoutering a very little problem that seemed to be so easy to solve.... I need to divide the array > A<-c(1:200) into two subsets at random. Therefore I use the function "sample" in R: > S<-sample(A,100) for a random sample of size 100. Then I need the values in A that are not selected in S to be put in another array, there is my problem! Is there anyway to do

Dear All, I am doing some exercise in statistics textbook on comparison of two experimental means. Is it possible to use t.test() do t-test when I have only two means, sample size, two standard deviations ? (no raw data). Thanks. Pramote

hi, I would like to subsample the array c(1:200) at random into ten subsamples v1,v2,...,v10. I tried with to go progressively like this: > x<-c(1:200) > v1<-sample(x,20) > y<-x[-v1] > v2<-sample(y,20) and then I want to do: >x<-y[-v2] Error: subscript out of bounds.

hi, I am trying to grow a classification tree on some data, but I have a little problem. In order to do so I have to use a function like "tree" in R and on the internet help(tree) I get the following: "The left-hand-side (response) should be either a numerical vector when a regression tree will be fitted or a factor, when a classification tree is produced" I would like to

I want to plot variation of more than one variable in single plot with different point types and points sizes . Can someone help me to do that, Thanks in advance. vinod ____________________________________________________________________________________ Now that's room service! Choose from over 150,000 hotels

Hi, I wanted to plot 2 lines on a single graph. Each graph has one axis that can be common. The code that I'm using is: ------------------------------------------------------- par(mfrow=c(1, 1)) x1 <- c(2, 4, 6, 8, 10, 12) x2 <- c(10, 20, 30, 40, 50, 60) y1 <- c(10,12,15,22,34,21) y2 <- c(40, 130, 150, 145, 40, 30) par(las=1, mar=c(4, 4, 2, 4)) plot.new()

Hi R People: Here is a simple set of commands: >x1 <- 1:10 >x2 <- sqrt(x1) >plot(x1) >points(x2,col="red",pch=3) >legend(2,8,legend=c("First","Second"),col=c("black","red"),pch=c(1,3)) > Fine. Now, I would like to put the legend box on the outside of the plot itself, perhaps in the lower left hand corner. I've been

Hi all I have run into a case where I don't understand why predict.lrm and predict.glm don't yield the same results. My data look like this: set.seed(1) library(Design); ilogit <- function(x) { 1/(1+exp(-x)) } ORDER <- factor(sample(c("mc-sc", "sc-mc"), 403, TRUE)) CONJ <- factor(sample(c("als", "bevor", "nachdem",

Dear all, I would like to take out the values from one vector that are equal to the values in another vector. Example: a <- c(1,2,3,4,5,6,7,8,9) b <- c(3,10,20,5,6) b_noRepeats = c(10,20) So I would like to have the vector b without the same values as vector a.

Hola compañeros de la lista. Estoy aprendiendo a usar el paquete "rsm" para superficies de respuesta. Siguiendo este ejemplo todo va bien, hasta que trato de obtener el valor máximo predicho para la variable de respuesta en los valores de x1 y x2 estimados. ------------------------------------------------------------- library("rsm") ChemReact CR <- coded.data(ChemReact,

hello, the example below does not work. (i know it's not supposed, but it makes it clear what i'm trying to achieve) par(mfrow=c(2,1)) xyplot(y~x2|x1,data=dataframe1,pch=20) xyplot(y~x2|x1,data=dataframe2,pch=20) i know i could probably merge the two datasets and do something like xyplot(y~x2|x1+dataset,data=merged) any other suggestion? thanks.

Hello, I am using e1071 to run support vector machine. I would like to plot the data with lattice and specifically show the hyperplanes created by the system. I can store the hyperplane as a contour in an object, and I can plot one object at a time. Since there will be thousands of elements to plot, I can't manually add them one by one to the plot, so I tried to loop into them, but only the

I'm trying to make a transition from S-plus under Windows to R under Linux. My immediate aim is to produce a scatter plot with two y-axes with different scales. That can be done in S-plus with a command of the following form: guiPlot( PlotType="Scatter", DataSet="execon", Columns="years,hstart,ship", AxisType="Multiple Y" ), where years, hstart, and

Hi, are there any plans to add a colorbar legend to image()? Or such a possibility already implemented which I just haven't discovered yet. Anyway, I will be willing to spent some time on the implementation if there isn't anyone working on that already.

Dear R-helpers, I am trying to construct a confidence interval on a prediction of a gam fit. I have the Wood (2006) book, and section 5.2.7 seems relevant but I am not able to apply that to this, different, problem. Any help is appreciated! Basically I have a function Y = f(X) for two different treatments A and B. I am interested in the treatment ratios : Y(treatment = B) / Y(treatment = A) as

Hello, I have difficulties combining boxes and lines in plot legend. I searched previous R-posts and found this (with no solution): http://tolstoy.newcastle.edu.au/R/help/06/07/30248.html. Is there a way to avoid boxes behind the line legends? x1 <- rnorm(100) x2 <- rnorm(100, 2) hist(x1, main = "", col = "orange",ylab = "density", xlab = "x", freq =

Dear List, I have a two-part question related to bpplot(), a box-percentile plot function in the Hmisc package. Take the example given in the Help for bpplot(), for instance. (1) How does one set but not draw the y-axis? What I did was, bpplot(... , yaxt="n"), but that apparently does not work (though it works for boxplot()). (2) How does one display the mean value of each variable

How do a plot several columns of a matrix at once in a single plot versus a single x-variable? The default plot.matrix or plot.dataframe commands plot each column versus each other column in several sub-plots. I want to plot each column versus a single other vector (x) as several lines or points in one plot. I can do it by hand: get the range of all variables (i.e. columns of the matrix or
