Hi, I am a newbie of R, and playing with the "ifelse" statement. I have the following codes: ## first, for(i in 1:3) { for(j in 2:4) { cor.temp <- cor(iris.allnum[,i], iris.allnum[,j]) if(i==1 & j==2) corr.iris <- cor.temp else corr.iris <- c(corr.iris, cor.temp) } } this code is working fine. I also tried to perform the same thing in another way with "ifelse":

Good afternoon list, I have the following character strings; one with spaces between the maths operators and variable names, and one without said spaces. form<-c('~ Sentence + LEGAL + Intro + Intro / Intro1 + Intro * LEGAL + benefit + benefit / benefit1 + product + action * mean + CTA + help + mean * product')
