runFastPCA {CytoTree} | R Documentation

## Calculate principal components in CYT

### Description

Calculate principal components in CYT

### Usage

    runFastPCA(object, center = FALSE, scale. = TRUE, verbose = FALSE, ...)

### Arguments

`object` | a CYT object
`center` | logical, a logical value indicating whether the variables should be shifted to be zero centered. Alternately, a vector of length equal the number of columns of x can be supplied. The value is passed to scale. See `fast.prcomp`
`scale.` | logical, a logical value indicating whether the variables should be scaled to have unit variance before the analysis takes place. The default is FALSE for consistency with S, but in general scaling is advisable. Alternatively, a vector of length equal the number of columns of x can be supplied. The value is passed to scale. See `fast.prcomp`
`verbose` | logical. Whether to print calculation progress.
`...` | Parameters passing to `fast.prcomp` function

### Value

A CYT object with PCA

### Examples

    cyt.file <- system.file("extdata/cyt.rds", package = "CytoTree")
    cyt <- readRDS(file = cyt.file)

    cyt <- runFastPCA(cyt, verbose = TRUE)
