Use for loop to plot multiple figures and output them to pdf file, But just get the last figure

pdf("test.pdf")
for (i in length(dis_pos)){
    fic <- chr1[ chr1$pos < dis_pos[i]+500 & chr1$pos >=dis_pos[i], ]
    plot(fic$pos,fic$count,type='h')
}
dev.off()

I wanted to plot many figures according to the length of variable dis_pos. And I just got the last figure in pdf file. I mean, If the variable dis_pos equals 12, how can I get all the 12 picture in test.pdf file, not the 12th figure?

What "did not work" in the first loop? Was there an error message? – neilfws Apr 20 '17 at 05:27
@Tw UxTLi51Nus Thanks. That's exactly the same question I face. – Shixiang Wang Apr 20 '17 at 05:35

How many plots did your for-loop create (without printing to pdf)? Hard to troubleshoot your code when no [reproducible example](http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) is provided. – Adam Quek Apr 20 '17 at 07:17
`i in 1:length(dis_pos)` not `i in length(dis_pos)`. – Axeman Apr 20 '17 at 07:45
@Axeman you got it. – Shixiang Wang Apr 21 '17 at 11:10
