[R] i need help for var.test()

[sait k]

Dear Sir or Madam,
i want to use the var.test() (f.test()) for n samples.
But in R the var.test() can only used for variances of two samples. In the intruductions stands:  Performs an F test to compare the variances of two samples from normal populations.
I need a variance test for n samples. It will be great, if you tell me the which test i can use in R for this problem.
Thank you for the help.
Yours sincerely,
