[R] Automatic creation of file names

Dear R-Help members,

I have a question about how to save to the hard drive the one thousand datasets I generated in a simulation. The datasets are created in a "for" loop that repeatedly creates normally distributed datasets, such as the example below:
Library(MASS)
for (number in 1:1000) {

dataset = mvrnorm(n = 400, mu = c(0,0,0),

        Sigma = matrix(c(1,0.3,0.3,0.3,1,0.3,0.3,0.3,1),3,3)) }

I don't know how to write the datasets with different names to the hard drive. I have solved the problem before by creating a list of names (file1.txt, file2.txt,file3.txt, etc...) in Microsoft Excel, reading it to R with read.table, and using write.table to write each file with the name I created in Excel.
I want to know if it is possible to create a list of file names automatically within R to save the datasets created in my simulation. Thank you for your help,

Walter L. Leite
