[R] [Help]:How to use "loop" to achieve this aim?

[qcshare]

Hello, Everyone,
how to use "loop" to make the process automatic and fast?
When compute each sample, the script type in R almost the same, just the
input and output file's name is changed(chr1 change to chr2, chr3,chr4...).

The first sample's script like this:
>chr1=MEDIPS.readAlignedSeqences(BSgenome="hg19", file="chr1",numrows= )
>chr1=MEDIPS.genomeVector(data=chr1, bin_size=50,extend=250)
...
...
>write.table(frameschr1.frame500.step250, file="frames.chr1.meth.txt",
sep="\T", quote=F, col.names=T, row.names=F)

The second sample's script like this:
>chr2=MEDIPS.readAlignedSeqences(BSgenome="hg19", file="chr2",numrows= )
>chr2=MEDIPS.genomeVector(data=chr2, bin_size=50,extend=250)
...
...
>write.table(frameschr2.frame500.step250, file="frames.chr2.meth.txt",
sep="\T", quote=F, col.names=T, row.names=F)

so, how to make this process automatic and fast?
Thanks~
