## Function to compute the PCAs for a given distance matrix

### Description

Function to compute the PCAs for a given distance matrix

### Usage

    calculatePCAs(distmat, pcas)

### Arguments

`distmat` | the distance matrix
`pcas` | 2-element vector of PCAs to include in results

### Value

the x slot limited to pcas after calling stats::prcomp on distmat

### Examples

    data("mouseData", package = "metagenomeSeq")
    aggdat <- aggFeatures(mouseData, level = "genus")
    distmat <- computeDistMat(aggdat, dist_method = "bray")
    calculatePCAs(distmat, c(1,2))
