Hello! Could you tell me how to write R programming code about "Test the hypothesis that £l=0.5 ?" Thank you! Cindy --- [[alternative HTML version deleted]]

Dear all, I have another question about fisher.test: Is there any way to save the resulting p-value in a matrix or file after a loop as below? for (i in 1:42) { # testing difference in income(pinc) between people in # (with in1=1) and out (with in1=0) of the program for # group i fisher.test(m$pinc[m$group==i], m$in1[m$group==i], workspace=40000000, hybrid=F)} When I run this loop, there is no

If you've 'rediscovered the web' with Firefox (http://getfirefox.com), you might find this tip handy. Suppose you want to search the (local) R documentation for information about the lme function. Wouldn't it be nice to just type into the browser address bar: r lme and have the search performed? Here's how (on Windows): Click on this link:

About six months ago there was a reference to a site (in french) that did a spectacular job of demonstrating R's graphical capabilities. My bookmarks were recently wiped and I cannot find this site despite my best googling. Anyone have the address which I have done a miserable job describing? Thanks. Michaell

Hello I've another question :-) I would like to transform a list to a integer. I must be sure that the number entered by the user is an integer! Thus, I've made : repeat{ cat("Effectif des populations (integer):") n<-scan("",n=1,what=list(0),quiet=TRUE) if (is.integer(n[[1]])==TRUE) break print("L'effectif des population doit etre un entier")

Hi, how can I produce random data which lies around a straight line with angle 45 degree.

Dear R users, I want to share my joy with you. Please see the following excellent introduction to R "Statistiques avec R " by Vincent Zoonekynd http://zoonek2.free.fr/UNIX/48_R/all.html In paticular, you can see a lot of fascinating graphics examples of R from which you can get many hints. Soryy if this is already well-known, but the CRAN search did not show nothing with the keyword

bonjour, Je suis actuellement en derniere annee d'ecole d'ingenieur en informatique et statistiques et je dois réaliser mon projet de fin d'études sur le logiciel R. En fait, je dois réaliser un scoring sous R puis le meme sous SAS et comparer les resultats. Mon fichier se prete à une regression logistique. J'ai donc utilisé la fonction glm sous R et Catmod sous SAS seumement, je

How can i plot an array and instead of having on the x labels the indexes of the array I want to display an other String array of the same length

Hi, how can I do multinomial logistic regression in R? I think glm() can only handle binary response variable, and polr() can only handle ordinal response variable. how to do logistic regression with multinomial response variable? Thanks __________________________________

Hi All, Thanks for you help, I have loaded the library MASS to call the mca. But when I want to do the mca, there is another problem, for example -------- -------- > leaf <- read.table("C:/Documents and Settings/wxh-c/×ÀÃæ/1.txt", + col.names=c("size","texture"),header=TRUE) > leaf size texture 1 3 3 2 2 2 3 3 2 4 3

Hi, I'm looking for a manual (we based or pdf) which would explain in detail with graphical examples what all the option can do in plot and par. Does anybody now anything like this? A couple of manuals to R I went through do have plot parameters mentioned, but sometimes it is hard to understand or imagine what the parameter can do (the same with the related help page) e.g. I met "From

I know this question is very simple, but I am not figure it out I have the data frame:   test<- data.frame(year=c(2000,2000,2001,2001),x=c(54,41,90,15), y=c(29,2,92,22), z=c(26,68,46,51)) test   year    x   y   z 1 2000 54 29 26 2 2000 41  2  68 3 2001 90 92 46 4 2001 15 22 51   I want to sum the vectors x, y and z within each year (2000

Is there an option to draw concentration ellipses in biplots ? It seems really nice to summarize large number of points of each group. Cheers../ Murli

Please could someone point me in the right direction as I appear to be having a total mental block with fairly basic PCA problem! I have a large dataframe where rows represent independent observations and columns are variables. I am wanting to perform PCA sequentially on blocks of nrows at a time and produce a graphical output of the loadings for the first 2 EOFs for each variable. I'm sure

My question is based on an example provided in the following: Referencing: Statistics with R Vincent Zoonekynd <zoonek at math.jussieu.fr> 6th January 2007 URL: http://zoonek2.free.fr/UNIX/48_R/all.html data(HairEyeColor) a <- as.table( apply(HairEyeColor, c(1,2), sum) ) # Provided Example barplot(a, beside = TRUE, legend.text = attr(a, "dimnames")$Hair) # I

Hello, I apologize for this question that may has been asked a lot of times but I could not go through it. I create a multivariate time series containing NA values. I want to compute a linear regression and obtain a time serie for both residuals and fitted values. I have tried the trick ts.intersect, without success. Could you help me out of this? #### Example: y<-ts(1:10+rnorm(10))

Hi, Since I started to make some 'final' plots of my data I found that I have tons of questions related to 'the little things'. Rather than bother the list with all the questions (ahem), or search the archives for similar questions and translate the context, I would like to find a FAQ for plotting in particular (and R programming in general). I know for sure (searching the
