How to write a data.frame into n different csv-files
...this one, but I can't write into ten different files, like test1.csv to test10.csv:
x <- rnorm(10)
y <- c(1:10)
z <- data.frame(y,x)
n <- nrow(z)
for (i in 1:n) write.csv(z$x[i], file="test[i].csv")
Can anyone help me?
Yours,
Guido

Recursive solution with for()
...the type x_1[t]=x_1[t+1]+beta*x_2[t], and used a for-loop
written
for(j in c(1:t-1, recursive=TRUE){
...
}
This didn't work, so i resolved to writing
for(j in c(10,9,...,1){
which worked, but is not terribly efficient. So, what did I do wrong?
Thanks in advance,

FYI: Package installation problem with windows
...drove me nuts because it wouldn't install new packages,
or more irritating still: It would chose randomly which packages to
install when given a list ("unable to move temporary installation" ).
The solution was to turn of the indexation of folders.
