## Intestinal microbiota diversity in 1006 western adults
The data set from [Lahti et al. Nat. Comm. 5:4344, 2014](http://www.nature.com/ncomms/2014/140708/ncomms5344/full/ncomms5344.html) has microbiota profiling of 130 genus-like taxa across 1006 normal western adults from [Data Dryad](http://doi.org/10.5061/dryad.pk75d). Load the data in R:
```{r data2, warning=FALSE, message=FALSE}
# Download the required R packages and then the HITChip Atlas data set
library(microbiome)
data(atlas1006)
```
Estimate ecosystem alpha diversity and related indicators for this data set:
```{r div-example, warning=FALSE, message=FALSE}
tab <- microbiome::alpha(atlas1006, index = c("shannon", "invsimpson"))
