[R] Newbie: Simple loops: complex troubles

I am used to java (well, i dont remember it really well, but anyway)

I have having a really difficult time making simple loops to work. I got the
following to work:

	##Creates objects Ux1, Ux2, Ux2 etc. that  all contain n numbers in a
random distribution
 	m<-c(m1,m2,m3,m4,m5,m6,m7,m8,m9,m10)#these are defined as numbers (means)
	v<-c(v1,v2,v3,v4,v5,v6,v7,v8,v9,v10)#these are defined as numbers
	for(k in 1:g)
		assign( paste("Ux", k, sep=""), rnorm( n  , 
assign(paste("m",1,sep=""),m[k])   ,   assign(paste("m",1,sep=""),v[k])  )  

The above seems like a lot of work for such a simple feat, no?

Also, I CANNot get the following to work in a loop manor:




Maybe I am just not using matrixes enough? but even that seems quite a lot
more complex than calling x<-matrix() then grabbing values by
x[j][k]...(java style if i remember correctly). the matrix help in R dosnt
make much sense to me. And also i am not sure why numeric() dosnt make you
define length before you use it, yet matrix() does.  Is there some other
funciton that i should be using to make length not an issue?

All in all, I dont know if i am going about this loop stuff a reaaaaly round
about way - Any help would make me much less loopy:Pthanks
