R: Root of singularity-corrected eigenvalue decomposition

tdecomp {fpc} | R Documentation

## Root of singularity-corrected eigenvalue decomposition

### Description

Computes transposed eigenvectors of matrix `m` times diagonal of square root of eigenvalues so that eigenvalues smaller than 1e-6 are set to 1e-6.

### Usage

      tdecomp(m)

### Arguments

`m` | a symmetric matrix of minimum format 2*2.

### Details

Thought for use in `discrcoord` only.

### Value

a matrix.

### Note

Thought for use within `discrcoord` only.

    y <- rnorm(10)
    z <- cov(cbind(x,y))
    round(tdecomp(z),digits=2)
