[R] write.table & csv help

[Petr Pikal]

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)

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
