threshrankfun {phyloseq} | R Documentation

## A closure version of the `threshrank` function.

### Description

Takes the same arguments as `threshrank`, except for `x`, because the output is a single-argument function rather than a rank-transformed numeric. This is useful for higher-order functions that require a single-argument function as input, like `transform_sample_counts`.

### Usage

    threshrankfun(thresh, keep0s=FALSE, ...)

### Arguments

`thresh` | A single numeric value giving the threshold.
`keep0s` | A logical determining whether 0's in `x` should remain a zero-value in the output. If FALSE, zeros are treated as any other value.
`...` | Further arguments passes to the `rank` function.

### Value

A single-argument function with the options to `threshrank` set.

### See Also

`transform_sample_counts`, `threshrankfun`, `threshrank`

### Examples

    data(esophagus)
    x1 = transform_sample_counts(esophagus, threshrankfun(50))
    otu_table(x1)
    x2 = transform_sample_counts(esophagus, rank)
    otu_table(x2)
    identical(x1, x2)
