how to create data.frame with dynamic count of values
I don't understand what you're asking for.
But if your goal is to create N1 through N15 in order to use them to
fill a data frame, then it can be much simpler:
items <- 15
VarSize <- 10
tmp <- matrix(0,nrow=VarSize,ncol=items)
tmp <- data.frame(tmp)
names(tmp) <- paste('N',seq(items),sep='')
## of course, this next only works if VarSize <= length(letters)
tmp$X1 <- letters[1:VarSize]
You could instead start with
tmp <- matrix( rnorm(VarSize*items) , nrow=VarSize , ncol=items)

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
