# Conform two community data tables

### Description

Conforms two community data tables to have the same set of columns (species)

### Usage

1 | ```
conformveg(x, y, fillvalue = 0, verbose=FALSE)
``` |

### Arguments

`x` |
Community data, a site-by-species matrix. |

`y` |
Community data, a site-by-species matrix. |

`fillvalue` |
The value to be used to fill new entries in inflated matrices. |

`verbose` |
Displays information about the number of species shared between |

### Details

This function adds to `x`

as many new columns as columns of `y`

that are not in `x`

. The same is done for `y`

, so the two tables have the same set of columns when they are returned.

### Value

A list with the two inflated matrices `x`

and `y`

.

## Loads data (38 columns and 33 species)
data(wetland)
dim(wetland)
## Splits wetland data into two matrices of 30x27 and 11x22
wetland.30 = wetland[1:30,]
wetland.30 = wetland.30[,colSums(wetland.30)>0]
dim(wetland.30)
wetland.11 = wetland[31:41,]
wetland.11 = wetland.11[,colSums(wetland.11)>0]
dim(wetland.11)
## Conforms the two matrices so they can eventually be merged
wetland.cf = conformveg(wetland.30, wetland.11)
dim(wetland.cf$x)
dim(wetland.cf$y)
names(wetland.cf$x)==names(wetland.cf$y)
