Hi,
I want to generate a number of vectors and store them with different names, like this:
x=1
while (x<100)
{
vector#x# = rnorm(100)
x=x+1
}
where each vector has, at its hand, instead of #x# a number which goes from 1 to 99.
How can I do this?
Thanks

?paste and ?assign but almost surely you'd be better off storing these vectors in a list or matrix.
Hallo,
x=1
while (x<100)
{
vectorx<- rnorm(100)
assign(paste("vector",x,sep=""),vectorx)
x=x+1
}
ls()

Before polluting your workspace with objects, look at how you might use a 'list' to collect them all together, especially if you are going to do processing on them later as a group, or if you want to easily save/load them. You could do the following:
myList <- list()
for (i in 1:10) myList[[paste('funny name', i)]] <- runif(10)
myList
$`funny name 1` [1] 0.26550866 0.37212390 0.57285336 0.90820779 0.20168193 0.89838968 0.94467527 0.66079779 0.62911404 [10] 0.06178627 $`funny name 2` [1] 0.2059746 0.1765568 0.6870228 0.3841037 0.7698414 0.4976992 0.7176185 0.9919061 0.3800352 0.7774452 $`funny name 3` [1] 0.93470523 0.21214252 0.65167377 0.12555510 0.26722067 0.38611409 0.01339033 0.38238796 0.86969085 [10] 0.34034900 $`funny name 4` [1] 0.4820801 0.5995658 0.4935413 0.1862176 0.8273733 0.6684667 0.7942399 0.1079436 0.7237109 0.4112744 .........
