_D_e_s_c_r_i_p_t_i_o_n:

     Covariance matrix for the bivariate Gaussian common component
     geostatistical model or its inverse, and optionally the
     determinant of the matrix.

_U_s_a_g_e:

     varcovBGCCM(dists.obj, cov0.pars, cov1.pars, cov2.pars,
                 cov0.model = "matern", cov1.model = "matern",
                 cov2.model = "matern", kappa0 = 0.5, kappa1 = 0.5,
                 kappa2 = 0.5, scaled = TRUE, inv = FALSE, det = FALSE)

_A_r_g_u_m_e_n_t_s:

dists.obj: ~~Describe 'dists.obj' here~~ 

cov0.pars: ~~Describe 'cov0.pars' here~~ 

cov1.pars: ~~Describe 'cov1.pars' here~~ 

cov2.pars: ~~Describe 'cov2.pars' here~~

  scaled: ~~Describe 'scaled' here~~ 

     inv: logical. If 'TRUE' the inverse of the covariance matrix is
          returned instead.  

     det: logical. Optional, if 'TRUE' the logarithm of the detarminant
          of the covariance matrix is returned as an attribute.  

_V_a_l_u_e:

     A matrix which is the covariance matrix for the bivariate Gaussian
     common component geostatistical model or its inverse if
     'inv=TRUE'. If 'det=T' the logarithm of the determinant of the
     matrix is also returned as an attribute named 'logdetS'.

_W_a_r_n_i_n_g:

     This is a new function and still in draft format and pretty much
     untested.
