Examples

# Initiate count matrix
x <- matrix(
  c(1500, 1300, 280, 356),
  ncol = 2
)
rownames(x) <- c("taxon1", "taxon2")
colnames(x) <- c("sample1", "sample2")

# Convert to tidytacos object
data <- create_tidytacos(x,
  taxa_are_columns = FALSE
)

# Add relative abundance
data <- data %>% add_rel_abundance()
