Hello folks, I am currently receiving a lot of emails from the list which proves that this is a very important place to get good feedbacks and tips and that the community is here to help .. Excellent thing. I am not though able to login to my subscriber space to change the email reception into daily digest, or I am not looking to the right place, if someone can point me to the right URL that

Hello All, I am writing to ask your opinion on how to interpret this case. I have two vectors "a" and "b" that I am trying to compare. The wilcoxon test is giving me a pvalue of 5.139217e-303 of a over b with the alternative "greater". Now if I make a summary on each of them I have the following > summary(a) Min. 1st Qu. Median Mean 3rd Qu.

Dear all, I'm using friedman rank test in R. I need to know which P value is used default and procedure to change the threshold P value. With regards jeevitesh

Hello, I'm running into a very strange problem: > xrange <- c(-2.5,2.5) > xdim <- 100 > mobility <- 0.1 > slope <- 1.16 > urange <- slope*xrange > udim <- max(slope*xdim,5) > du <- (urange[2]-urange[1])/udim > uvec <- urange[1]+(1:udim-0.5)*du > # type dependent weight function > ckern <-

Hi everybody, I noticed a strange behavior when using loops versus apply() on a data frame. The example below "explicitly" computes a distance matrix given a dataset. When the dataset is a matrix, everything works fine. But when the dataset is a data.frame, the dist.for function written using nested loops will take a lot longer than the dist.apply ######## USING FOR ####### dist.for

Dear useRs, i have certain commands for some operations in R. They are good if you have a small dataset but my dataset, apart from what i used in the recent past, is prety large. I want to convert these massive sets of commands into a simple loop. Your help is required on it thanks in advance eliza kindly note: "e" is matrix whose each column has to be executed into a distance vector

The print method for lme *prints out* the fitted correlation matrix for the random effects. Is there any way to get these values as an object in R? I have examined the components of the lme object (called "junk" in the example below) and the components of summary(junk) without finding these numbers. (How I did this: I dumped the entire lme object to a text file and then used egrep to

Hi, I am trying to place my own functions in the nlme environment: The following statement works: environment(coef.corSPT) <- environment(getS3method("coef","corSpatial")) but this one returns an error: environment(get("coef<-.corSPT")) <- environment(getS3method("coef<-","corSpatial")) Error in

Dear All, there seems to be some strange influence of the Design package on data.frame. If I build a data.frame containing a Surv object without loading the package Design, the data frame is usable to coxph. If instead I just load Design and build a data.frame afterwards, the naming of the Surv object is different and it does not work with coxph. (In my real application I loaded Design to use the

tl;dr: S3 lookup no longer works in custom non-namespace environments as of R 3.6.1. Is this a bug? I am implementing S3 dispatch for generic methods in environments that are not packages. I am trying to emulate the R package namespace mechanism by having a ?namespace? environment that defines generics and methods, but only exposes the generics themselves, not the methods. To make S3 lookup work

I have code that creates the same matrices , "a" and "b". The code creating "a" is not in a function and the code creating "b" is in a function. I would like to do operations on "b" like I can on "a", however I can't figure out how I can return a matrix (or data frame) from a function. Thanks for your help! > r <- 5; c <- 5

Hello, I am trying to do a multi-dimensional scaling of the World Bank's quality of governance indicators for the Balkan region. I am having trouble labelling my plot.

Hi, guess my problem has simple solution. I want to extract ONLY Std. Errors of Max. Lik. estimates (my_fit<-mle(object,...)), the same as I can do with estimates by: x<-as. matrix(coef(my_fit)). I could not find any function similar to 'coef(my_fit)', which extracts only Standard Errors. So far all I can do is to type: summary(my_fit) and then get the whole output (with Standard
