## Summarize amino acid position

### Description

List HLA alleles and amino acid residues at a given position.

### Usage

    summariseAAPosition(hla_calls, aa_pos, aln = NULL, na.rm = FALSE)

### Arguments

`hla_calls` | HLA calls data frame, as returned by `readHlaCalls` function.
`aa_pos` | String specifying gene and amino acid position, example `"A_9"`.
`aln` | Matrix containing amino acid sequence alignments as returned by `readHlaAlignments` function. By default function will use alignment files shipped with the package.
`na.rm` | Logical flag indicating if `NA` values should be considered for frequency calculations.

### Value

Data frame containing HLA alleles, their corresponding amino acid residues and frequencies at requested position.

### Examples
