similar to: Renaming variables

Hello, I would like to select cases using multiple logical operations (e.g. X or Y or Z) without having to repeat the dataframe$variable within the subscript. My working code (with a single logical operator) currently looks like this: dataframe$newvariable[data$oldvariable=="X"]<-"group1" I thought this next line of code might do what I wanted, but it doesn't:

Hi, I am trying to reshape data from a long to wide format but have a specific task that I cannot get to output properly. # SAMPLE DATA; id <- c(1,2,2,3,3,3) time <-c(0,0,5, 0, 2, 10) x <- rnorm(length(id)) long <- data.frame(id,time,x) # To reshape, I would like to exclude 'id' values that have NO duplicate (i.e., remove # id=1 in this case). My attempts failed because the

Hello, I am a (relatively) experienced programmer, but new to R. I have a problem using R 1.9.1. I have fit some data using glm(), from within a function: formula = as.formula(paste(depvarname, "~", rhs), env=globalenv()) return (glm(formula, family=binomial(link=logit))) I have now come back to the formula and want to add some more variables to it. So I do:

Hi! I'm using a large panel data, and now I have faced some difficulties with my analysis. The predictors are not normally distributed and there are quite many outliers (some of them are influential though). I have tried to change the logarythm, but i'm not sure, how to do that. I want also draw a plot picture in which logarythms of predictors x and y are changed. How could I do that?

Hi All, I am addressing this post to all who are new to R. When learing R in the last weeks I took some notes for myself to have code snippets ready for the data analysis process. I put these snippets together as a script template for future use. Almost all of the given command prototypes are tested. The template script contains snippets for best practices and leaves out the commands that

Hi, I have this controller method that I need to test: def link_concept_to_client concept_to_link = Concept.find(params[:concept_id]) # take all the variations for the concept for variation in concept_to_link.variations new_client_variation = ClientVariation.new new_client_variation.client = session[:active_client] new_client_variation.variation = variation
