Dear list, I am still struggling with something that should be easy: I compare two data frames with a lot of common rows and want to keep only rows that are NOT in both data frames, unique. Here are an example of these data frame. reported <- structure(list(Product = structure(c(1L, 1L, 1L, 1L, 2L, 2L, 3L, 4L, 5L, 5L), .Label = c("Cocoa", "Coffee C", "GC",

Hi! I use simtest fonction of multcomp package to compile a Dunnett's test. I have 10 treatments and one control group, so i create a matrix with: m<-matrix(0,10,11) m[1,1]<--1 m[1,2]<-1 m[2,1]<--1 m[2,3]<-1 m[3,1]<--1 m[3,4]<-1 m[4,1]<--1 m[4,5]<-1 m[5,1]<--1 m[5,6]<-1 m[6,1]<--1 m[6,7]<-1 m[7,1]<--1 m[7,8]<-1 m[8,1]<--1 m[8,9]<-1

Hi, In KubeVirt we are right now starting libvirt via a wrapper shell script. I want to remove that wrapper and directly start libvirtd from our golang code. This means that our golang code is PID 1 in the container and we start libvirtd as a fork from there. When I did this, strange things started to happen. Libvirt was still able to start and manage qemu processes, but stopping the qemu

Dear list, I tried to use the nparcomp to run some post hoc non-parametric comparison and got and error.

Dear R-experts, I need to replace the values of a vector(tx) with a word ('Vehicle') when the value of the vector contains the word 'vehicle'. Sometimes, the value could be 'MCT vehicle', or 'control-vehicle', etc. I tried gsub like this treatment<-gsub('vehicle','Vehicle', tx, ignore.case=T) But then I end up with values like 'MCT

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. I could not get any response. I formulated the following code of FIML to analyse univariate sample selection problem. Would you please advise me where is my problem library (sem) library(nrmlepln) Selection

I am working on creating an R package for doing fire department analysis and am trying to create a function that can display emergency incident densities. The following code sort of does the trick, but I need a display that shows the number of incidents per square mile. I believe the code below shows incidents per square unit (in this case, degrees lat/long). To solve this problem, I believe

I''m trying to get substring from a utf-8 encoded string. (say, first 50 characters of the string) String#[0..49] would give me the first 50 bytes not 50 characters.. I know there is jcode library, but it only let you count number of characters in utf-8 string. unicode gem doesn''t seem to help much. unicode_hacks gem seem to solve the problem, but it also seems to

On p. 48 of "Statistics Complements" to the 3rd MASS edition, http://www.stats.ox.ac.uk/pub/MASS3/VR3stat.pdf I read that the orthogonal rotations of Z Lambda^-1 remain uncorrelated, where Z is the PC and Lambda is the diag matrix of singular values. However, the example below that text is > A <- loadings(ir.pca) %*% diag(ir.pca$sdev) If ir.pca$sdev are the singular values,

Dear List, I want to compare and return the rows which are NOT in the two data frames. Classic methods don't work as the df have NOT the same dimensions. Here are one example of my df: reported <- structure(list(Product = structure(c(1L, 1L, 1L, 1L, 2L, 2L, 3L, 4L, 5L, 5L), .Label = c("Cocoa", "Coffee C", "GC", "Sugar No 11", "ZS"),

Hello, I have an application that access two different DBMS - Firebird and Postgres. So far, that''s ok. The problem is, depending on the customer logged, a different database (Firebird) must be selected. To make the things clearer: Postgres: 1 database shared by all customers with these tables: - user - vehicle - driver Firebird: several databases with different names and identical
