betaBlock: Sample fixed effect coefficients
In bpnreg: Bayesian Projected Normal Regression Models for Circular Data

Sample fixed effect coefficients

1	betaBlock(Omega, R, theta, X, Z, p, A, N)

`Omega`	current covariance matrix
`X`	design matrix model parameters (differs per person)
`Z`	design matrix for random effects (differs per person)
`p`	dimension X (number of columns/variables+indicator variables)
`A`	prior variance of fixed effect coefficients
`N`	sample size at second level
`Y`	current outcome vector (Y.I=cos(theta)R, Y.II=sin(theta)R)
