Hello,

From a IRange object:

```
ir <- IRanges(c(1,3,5,7,7,9),width=c(4,2,1,2,2,2))
```

I know how to plot the corevage

```
cov <- coverage(ir);plot(cov)
```

I would like to know how to calculate the mean coverage for a window of x bases (5 bases in this example). I don't know how to do it.

Any tips?

Thank,
