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) -Don At 5:17 PM +0100 12/8/06, Knut Krueger wrote: >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. -- -------------------------------------- Don MacQueen Environmental Protection Department Lawrence Livermore National Laboratory Livermore, CA, USA ______________________________________________ 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.
