calculateF {HPiP} | R Documentation

## Calculate F1 or F2 Descriptors

### Description

This function calculates F1 or F2 descriptors:

- `F1` - sum of squared length of Single Amino Acid Repeats (SARs) in the entire protein sequence.

- `F2` - maximum of the sum of Single Amino Acid Repeats (SARs) in a window of 6 residues.

### Usage

    calculateF(x, type = c("F1", "F2"))

### Arguments

`x` | A data.frame containing gene/protein names and their fasta sequences.
`type` | The descriptor type: `F1` or `F2`.

### Details

calculateF

### Value

A length 20 named vector for the data input.
