For loops in R
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)

Is there any function to read genbank flat files.
Hi
I am trying to read genbank est flat files. Is there any function in R to do
that. I was looking for something similar to SeqIO.parse(input_handle,
"genbank") in bioPython that convert the genebank sequence into fasta
sequence.
(One option is to call biopython from R but I am not familiar with python
functions so I want to avoid that and I am keeping it as last resort)
Thanks and

scratch.
