89180768,MDU6SXNzdWU4OTE4MDc2OA==,437,bit of code missing in documentation (http://xray.readthedocs.org/en/latest/io.html#combining-multiple-files),2539828,closed,0,,1172685,1,2015-06-18T02:34:08Z,2015-06-22T15:44:59Z,2015-06-22T15:44:59Z,NONE,,,,"in [http://xray.readthedocs.org/en/latest/io.html#combining-multiple-files](http://xray.readthedocs.org/en/latest/io.html#combining-multiple-files) there is a bit of code missing in the function `read_netcdfs`: instead of: 

```
def read_netcdfs(files, dim, transform_func=None):
    def process_one_path(path):
        # use a context manager, to ensure the file gets closed after use
        with xray.open_dataset(path) as ds:
            # transform_func should do some sort of selection or
            # aggregation
            if transform_func is not None:
                ds = transform_func(ds)
            # load all data from the transformed dataset, to ensure we can
            # use it after closing each original file
            ds.load()
            return ds

    paths = sorted(glob(files))
    datasets = [process_one_path(p) for p in paths]
    xray.concat(datasets, dim)
```

it should be: 

```
def read_netcdfs(files, dim, transform_func=None):
    def process_one_path(path):
        # use a context manager, to ensure the file gets closed after use
        with xray.open_dataset(path) as ds:
            # transform_func should do some sort of selection or
            # aggregation
            if transform_func is not None:
                ds = transform_func(ds)
            # load all data from the transformed dataset, to ensure we can
            # use it after closing each original file
            ds.load()
            return ds

    paths = sorted(glob(files))
    datasets = [process_one_path(p) for p in paths]
    dset = xray.concat(datasets, dim)
    return dset
