Hello r helpers! Below is the whole coding for my programme. Before proceed more further, let me explain for you. First of all, I need to compute trimmed mean. Till that step is ok. Then I need to compute ssdw which is sum of square deviation. If I do equal trimming at both tail of distribution that I chose, I will use the first ssd formulae which is "a". But if I am doing unequal

Hello, I have a statistical problem that I am using R for, but I am not making sense of the results. I am trying to use multiple regression to explore which variables (weather conditions) have the greater effect on a local atmospheric variable. The data is taken from a database that has 20391 data points (Z1). A simplified version of the data I'm looking at is given below, but I have a

Hi, I'm analysing a dataset in which the same 5 subjects (male.pair) were subjected to two treatments (treatment) and were measured for 12 successive days within each treatment (layingday). Overall 5*2*12=120 observations. I want to test the effect of treatment, time (layingday) and their interaction. I have done so through the ANOVA below: >

hi there, I 'm a newbie in "VOIP technologies" ; i 'm implementing asterisk and i 'm wonder what is the best way to resolving "the Asterisk/NAT problem" : some clients are behind a NAT. anyone could help me? thanks johanna _________________________________________________________________ Appelez vos amis de PC ?

Hi all: I have a question about lm on t-test. data(sleep) I wanna perform t-test to test the difference between the 2 groups: I can use: t.test(extra~group) The t.test result shows that:t = -1.8608; mean1=0.75,mean2=2.33 But I still wanna use: summary(lm(extra~group)) Intercept=0.75,which is mean1,just the same as t.test. group2=1.58 means the difference of the 2 groups,so

I have recently "printed" in R to a postscript file. I'm working on a SSH without an X terminal. It was fairly automatic: > plot(x,y) > dev.off() And then the default creates a file called Rplots.ps which I can ftp to my laptop and open in Ghostscript. I can see the file, and nothing looks odd. However, when I import it into LaTeX, it refuses to configure right side up.

When I submit more than one batch file (same programs, different parameter values, huge simulations, different result names) the only results that get saved are from the *last* batch file to finish. They are all being run in the same subdirectory (so same .RData file?) I've done: R --save BATCH infile outfile and I've also put q(save="yes") at the end of the program, but

Dear all! After hours of trying around, I gave up: I have a 2-dimensional array, and I know how to split it into its rows and how to get the mean for every row using 'sapply'. But what I want is to calculate the mean over the first n rows, and then the second n rows, etc., so that I get a vector like: v == mean1(row 1:5), mean2(row6:10),... (trivial, you might say. I find it rather

Hey, Have i done something wrong or is there something wrong with latest CVS and cdr_mysql, cause after checking out latest CVS today, I got warning: [cdr_mysql.so]WARNING[1074424544]: File loader.c, Line 226 (ast_load_resource): /usr/lib/asterisk/modules/cdr_mysql.so: undefined symbol: uncompress WARNING[1074424544]: File loader.c, Line 345 (load_modules): Loading module cdr_mysql.so failed!

Hi! How can I get around in R 2.5.1 in Windows: Error in strsplit(linebuffer, "") : object "linebuffer" not found It comes a few lines after the actual strsplit, and yesterday everything was fine… Thank you in advance Kindest regards, ******************************************************************* Johanna Hasmats Ph.D Student Royal Institute

I want to obtain a barplot with error bars and a mean plot with error bars with other scale on the left in the same plot. I need help to get the same x axis (centered) when overlay two plots (barplot2 and plotCI (or lineplot.CI) with errorbars), with diferent y axis. I use par (new=T) but the X axis names are not centered with the figures. An example of my data:

I have a rather basic question. How can I get R to generate a ANOVA table and a f-value for a hypothesis test such as: Data: group1 values: 5.2 4.5 6.0 6.1 6.7 5.8 group2 values: 6.5 8.0 6.1 7.5 5.9 5.6 ... H0: mean1 = mean2 = mean3 = mean4 HA: at least two means different where I want to evaluate using a f test statistic? F = MSTr/MSE I'd like a table similar to one that

Dear All I want to generate variable with Bivariate Normal Distribution by use mean1 = a, variance1 = b, mean2 = c, variance2 = d, rho = e. How I can do this. Many Thanks. IRD [[alternative HTML version deleted]]

Hello, Is it possible to draw level lines on the surface of a bivariate function? In the following example, to draw surface and levels lines for a multivariate normal law, I use persp, trans3d, contourLines and lines, but if the lines are correctly drawn, some parts of them are, of course, visible even if they are drawn on a non visible "face". Any suggestion to avoid this problem

Did the MASS package disappear? Specifically, I'm looking for a function to find the MCD (robust measure of shape and location) for a multi-dimensional data matrix. Anyone know anything about this?

Hi, all. I know that this is probably something that others have asked, but I can't find a reference in either the FAQ or the help pages. I'm trying to find a way to put Greek letters as a label of the plot *with* a value from the data. Previously I've used pasted and the word "rho". * paste("rho=", cor2[i]) will produce a label of

Buenas noches Tengo una base de datos a la cual le debo eliminar los valores NA y los valores iguales a 99, 98 y mayores de 10000000. Los valores NA los elimine con la función is.na, pero no tengo idea de como eliminar los valores anteriormente mencionados del vector de datos. Gracias [[alternative HTML version deleted]]
