df	The dataframe containing the data to convert.
threshold	The threshold that defines presence (presence if >= threshold)
col2convert	A vector of the columns to convert. Default is all the columns but the first, which contains an age, a depth or a sampleID.

Value

A vector of unique taxonIDs.

Examples

df <- data.frame(matrix(1:25, ncol = 5))
colnames(df) <- paste(rep("col", 5), 1:5, sep = "")
