Dear all, I have an error message, when I try to convert a zoo object (called test) to ts (on R 2.4.0, Package zoo version 1.2-1, Windows XP) > test 1994-05-10 1994-06-09 1994-07-09 0.0024943889 0.0024881824 0.0006955831 > str(test) atomic [1:3] 0.002494 0.002488 0.000696 - attr(*, "index")=Class 'Date' num [1:3] 8895 8925 8955 > is.regular(test) [1] TRUE

Hi, I have created a plot using filled.contour() and have the problem that one of the axis titles and an axis label are overlapping. I have tried changing par()$mgp (with, e.g. par(mgp=c(4,1,0)) ), but this just makes the title go off the screen. I can't work out how to make the plot take up less space in the window, so I can hopefully change mgp and sort the problem. Is changing mgp the only

Hola a todos, Os pongo aquí debajo un pequeño fragmento de código. Resulta que dispongo de una CADENA que tiene dos columnas. Una con palabras y la otra que dice si es bueno o malo. En otra variable tengo una LISTA. Quiero cruzar todas las palabras de la lista con todas las de la cadena y cuando alguna coincida, que me indique en qué fila está y también si la palabra es "buena" o

Hi, I have a large amount of data that I would like to create a histogram of and plot and do things with in R. It is pretty much impossible to read the data into R, so I have written a program to bin the data and now have a list of counts in each bin. Is it possible to somehow import this into R and use hist(), so I can, for instance, plot the probability density? I have looked at the help page

Dear Rusers, I'd like to take the cases of cancer of the larynx in chorley(spatstat) to explain my question. I want to join the points of cancer of the larynx with the disused industrial incinerator to generate lines, and then calculate the angles of these line comparing the horizontal line? How can i get it? It seems to be difficult to get the angles Thanks a lot. -- With Kind

Hi, i have never really used R before and i need to produce a density curve for use in an assignment. Following the instructions in the manual provided with my course i keep getting this error message: "Error in plot.xy(xy, type, ...) : invalid plot type '1'" The commands i have entered are: >x=seq(0, 1800, 10) >x >f=dnorm(x, 1454.190, 162.6301) >f

Yes, I don't know how to copy the plot on Mac and paste on to Word because you can't right click on the graph and say "copy as metafile."

Hi, I just installed R, I'm work in UBUNTU and I don't have idea about how to run a r-code written in emacs into the shell. Well I am in a shell, and obviously I can run simple commands over there, Must I compile the program? if yes, How must I do that? what is the extension? I really appreciate your help -- View this message in context:

Taking the Grunfeld data, which is built-in in R, for example, (1)How can I construct a dataset (or dataframe) that consists of the data of all firms in 1951? (2)How can I calculate the average capital in each form over the period 1951-1954? What I can imagine is to categorize the data by firm, and then select the data between 1951 and 1954 for each firm, but how can I do it? Thanks, Miao

enclosed a simple R script (and a data file, and the output) , with calls lda similar to the example with the iris data in the documentation. it is not working and i dont understand the error message. can anybody help me? i am using R 1.5.1 (2002.06.17) on debian woody stable. I would like to avoid updating now, because i want to keep the system in "stable". can somebody test, if the

Hi I have a set of data with both quantitative and categorical predictors. After scaling of response variable, i looked for multicollinearity (VIF values) among the predictors and removed the predictors who were hinding some of the other significant predictors. I'm curious to know whether the predictors (who are not significant) while doing simple 'lm' will be involved in

Dear list members, I am trying to estimate parameters of the AR(1)-GARCH(1,1) model. I have one additional dummy variable for the AR(1) part. First I wanted to do it using garchFit function (everything would be then estimated in one step) however in the fGarch library I didn't find a way to include an additional variable. That would be the formula but, as said, I think it is impossible to add

Hello everyone, I am searching for a covariate selection procedure in a cox model formulated as a counting process. I use intervals, my formula looks like coxph(Surv(start,stop,status)~ x1+x2+...+cluster(id),robust=T) where id is a country code (I study occurence of civil wars from 1962 to 1997). I'd like something not based on p-values, since they have several flaws for this purpose. I turned

Hallo, I have this dataset with repeated measures. There are two within-subject factors, "formant" (2 levels: 1 and 2) and "f2 Ref" (25 levels: 670, 729, 788, 846, 905, 1080, 1100, 1120, 1140, 1170, 1480, 1470, 1450, 1440, 1430, 1890, 1840, 1790, 1740, 1690, 2290, 2210, 2120, 2040, 1950), and one between-subject factor, lang (2 levels:1 and 2).

Hello All: I am trying to replicate the results of an example found in Alan Agresti's "Categorical Data Analysis" on pages 267-269. The example is one of a 2 x 2 cross-classification table of ordinal counts: job satisfaction and income. I am able to get Agresti's results for the independence model (G^2 = 12.03 with df = 9) assuming as he does that the data is nominal, but
