# a dataset from a censored Gaussian graphical model
n <- 100L
p <- 3L
Z <- rcggm(n = n, p = p, probl = 0.05, probr = 0.05)

rowNames(Z)
rowNames(Z) <- list(Y = paste0("i", seq_len(n))) 
# the same as rowNames(Z)$Y <- paste0("i", seq_len(n))
rowNames(Z)

colNames(Z)
colNames(Z) <- list(Y = paste("Y", 1:p, sep = ":"))
# the same as colNames(Z)$Y <- paste("Y", 1:p, sep = ":")
colNames(Z)

# a dataset from a  conditional censored Gaussian graphical model
