mx_rbind_all: Combine two species abundance matrices
In phytomosaic/ecole: ecole: School of Ecology Package

Description Usage Arguments Details Value See Also Examples

Cleanly combine two species abundance matrices by binding rows and filling zeros in empty cells.

1	mx_rbind_all(xx, yy)

`xx`	first array of species data, where rows = SUs and cols = species
`yy`	second array of species data

Top rows are from first matrix xx, bottom rows are from second matrix yy. All names of original sample units and species are retained. Zeros fill empty cells.

Matrix or data.frame containing all combined species and SUs.

rbind.fill from package plyr, and rbind_all from package dplyr.

# species abundance data
set.seed(1917)
spe <- data.frame(matrix(rnorm(30, 10, 50), 10, 3))
spe[spe < 0] <- 0
colnames(spe) <- c('Acer rubrum','Acer saccharum','Acer negundo')
spe
mx_valid(spe) # expect TRUE
spe[,2] <- 0
spe[4,] <- 0
mx_valid(spe) # expect FALSE
