[R] For loops in R

[cjmr]

Hello.

I've just started using R and am trying to figure out if the two codes
snippets below have the same output

gBest<-floor(runif(popsize,min=1,max=top))
velocity[i,j]<<-.4* velocity[i,j] + 1 * runif(1) * (pbestsVar[i,j] -
popVar[i,j]) + 1 * runif(1) * (archiveVar[gBest,j] - popVar[i,j])

and 

for (i in 1:popsize) {	
		for (j in 1:maxvar) {
			gBest<-sample(top,size=1)			
			velocity[i,j]<<-.4* velocity[i,j] + 1 * runif(1) * (pbestsVar[i,j] -
popVar[i,j]) + 1 * runif(1) * (archiveVar[gBest,j] - popVar[i,j])
			#velocity[i,j]<-.4* velocity[i,j] + 1 * .3722 * (pbestsVar[i,j] -
popVar[i,j]) + 1 * .3722 * (archiveVar[3,j] - popVar[i,j])
		}

many thanks
