[R] change the name of file

Dear R Users,
Is it possible to make file names dependent on a changing variable?
For instance. I generate random numbers in a loop and at each iteration I
want data to write to file (I do not want to write everything in one file
using 'append'):

for (i in 1:50){
x<-matrix(runif(100, min=0,max=1),nrow=5,ncol=20)

Of course file name Data_i.txt will be the same for changing i,

Any suggestion would be appreciate
