# Bray-Curtis distance

### Description

Returns the Bray-Curtis (also known as Sorenson, 1 - percent similarity) pairwise distances for the objects in the data. It has been superseded by distance() but remains for backward compatibility.

### Usage

1 |

### Arguments

`x` |
matrix or data frame with rows as samples and columns as variables (such as species). Distances will be calculated for each pair of rows. |

`rmzero` |
If rzero=TRUE, empty rows will be removed from the data before distances are calculated. Otherwise, the distance between two empty rows is assumed to be 0 (the default). |

### Value

This function returns a column-order lower-triangular distance matrix. The returned object has an attribute, Size, giving the number of objects, that is, nrow(x). The length of the vector that is returned is nrow(x)*(nrow(x)-1)/2.
