Dear All, I'm wondering if there is a R function could give me all the combinations of the grouping/cluster result, given the number of the groups. e.g. 3 objects: x1 x2 x3, number of groups is 2 so the result will be group1:x1,x2; group2: x3 group1: x1;group2: x2,x3 group1: x1,x3;group2: x2 many thanks yan

Dear R users/developers I requested help to solve the problem of formulating Multivariate Sample selection model by using Full Information Maximum Likelihood (FIML)estimation method.

Dear R-Users, I have a problem with an algorithm that iteratively goes over a data.frame and exclude n-columns each step based on a statistical criterion. So that the 'column-space' gets smaller and smaller with each iteration (like when you do stepwise regression). The problem is that in every round I use a new subset of my data.frame. However, as soon as I "generate" this

I would like to run a loop in R. I have never done this before, so I would be very grateful for your help ! 1. I have a sample set: 25 objects. I would like to draw 1 object from it and use it as a test set for my future external validation. The remaining 24 objects I would like to use as a training set (to select a model). I would like to repeat this process until all 25 objects are used as a

Dear all, Very simple question, but apparently uneasy to solve in R: I have a sampling of a variable x: (3, 4. 5, 2, ...) I want to know: - the mean <x> -> mean(x) - the uncertainty on <x> -> std.error(x) ? Or sd(x)? - the standard deviation of x -> ? - the uncertainty on the standard deviation -> ? Anyone has an idea? Thanks in advance,

I need to understand how and why dcast() adds NAs to a data frame that contained no missing values. The database table of chemical concentrations has all missing values removed because they cannot contribute to data analyses. The structure of the R data frame of these data have no NA values, and neither does the data frame resulting from applying the reshape2 melt() function to it. However,

Are they the same with .RData being the newer format?? Thanks, ...Tao

Hi, Could you please advice some easy way to do the following for a dataframe (header=F) having unequal column- & row- length. 1.

Hi, I'm trying to user lmer function from lmerTest package because, if I understood correectly, it allows to make better inference than lmer method from lme4 package. However, whatever I do I keep getting this error: Error in lme4::lFormula(formula = mark ~ ssCount + sTime+ : rank of X = 1660 < ncol(X) = 1895 any ideas what could be a problem? thanks, Srecko [[alternative HTML
