Hello R-Group I found how to fill the data.frame -> http://finzi.psych.upenn.edu/R/Rhelp02a/archive/70843.html
N1 <- rnorm(4) N2 <- rnorm(4) N3 <- rnorm(4) N4 <- rnorm(4) X1 <- LETTERS[1:4] ################### nams <- c(paste("N", 1:4, sep = ""), "X1") dat <- data.frame(lapply(nams, get)) names(dat) <- nams dat But I need also to create a dynamic count of numeric vectors items = 15 VarSize <-10 N1 <- rep(0,VarSize) N2 <- rep(0,VarSize) N3 <- rep(0,VarSize) N4 <- rep(0,VarSize) N5 <- rep(0,VarSize) ... N15<- rep(0,VarSize) # 15 items Thank you in advance Knut ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
