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

[Jeffrey Spies]

Correcting Karena's solution:

for(i in 1:22) {
chrn <- paste("chr",i,sep="")

chrn=MEDIPS.readAlignedSeqences(BSgenome="hg19", file=chrn,numrows=
?????)  # no quotes around chrn
chrn=MEDIPS.genomeVector(data=chrn, bin_size=50,extend=250)
frames=????? # I don't know how you get this variable
...
out_file <- paste("frames.chr", i, ".meth.txt", sep="") # dynamic file name
write.table(frames, file=out_file, sep="\t", quote=F, col.names=T,
row.names=F) # use var you just made
}

Replace the ???s.

Jeff.
