Hi, How can I produce the following output in .csv format using write.table function. for(i in seq(1:2)) { df <- rnorm(4, mean=0, sd=1) write.table(df,"C:/output.csv", append = TRUE, quote = FALSE, sep = ",", row.names = FALSE, col.names = TRUE) } Current O/p: x 0.287816 -0.81803 -0.15231 -0.25849 x 2.26831 0.863174 0.269914 0.181486 Desired output x1 x2 0.287816 2.26831 -0.81803 0.863174 -0.15231 0.269914 -0.25849 0.181486 Thanx in advance Sachin --------------------------------- [[alternative HTML version deleted]]

Hi I am not sure about what you want to achieve by sequential writing to a file so maybe you could fill an object in a loop and write it only once. df<-data.frame(matrix(nrow=4,ncol=2)) for(i in seq(1:2)) { df[,i] <- rnorm(4, mean=0, sd=1) } write.table(df,"output.csv", quote = FALSE, sep = ",", row.names = FALSE, col.names = TRUE) HTH Petr From: Sachin J <sachinj.2006_at_yahoo.com> Date: Tue 27 Jun 2006 - 04:34:36 EST Hi, How can I produce the following output in .csv format using write.table function. for(i in seq(1:2)) { df <- rnorm(4, mean=0, sd=1) write.table(df,"C:/output.csv", append = TRUE, quote = FALSE, sep = ",", row.names = FALSE, col.names = TRUE) } Current O/p: x 0.287816 -0.81803 -0.15231 -0.25849 x 2.26831 0.863174 0.269914 0.181486 Desired output x1 x2 0.287816 2.26831 -0.81803 0.863174 -0.15231 0.269914 -0.25849 0.181486 Thanx in advance Sachin ---------------------------------------------------------------------- ---------- [[alternative HTML version deleted]] ---------------------------------------------------------------------- ---------- R-help at 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 Petr Pikal petr.pikal at precheza.cz
