dimnames.datacggm: Dimnames of a “datacggm” Object

Description

Retrieve or set the dimnames of a “datacggm” object.

Usage

# S3 method for datacggm
dimnames(x)
# S3 method for datacggm
dimnames(x) <- value

Arguments

x

an object of class ‘datacggm’.

value

a nested list with names ‘X’ and ‘Y’. See below for mode details.

Details

For an R object ‘x’ of class ‘datacggm’, dimnames retrieves or sets the dimnames attribute for the matrices Y and X (see ‘datacggm’ for more details). When setting the dimnames attribute, value$Y can be NULL (which is not stored) or a list of length two. In the last case, value$Y is passed to the method function dimnames for setting the dimnames attributes of the matrix retrieved by getMatrix(x, "Y"). In the same way, value$X can be used for setting the dimnames attributes of the matrix retrieved by getMatrix(x, "X").

Examples

set.seed(123)
# a dataset from a censored Gaussian graphical model
n <- 100L
p <- 3L
b0 <- rep(0, p)
Z <- rcggm(n = n, b0 = b0, probl = 0.05, probr = 0.05)
dimnames(Z)

dimnames(Z) <- list(Y = list(paste0("i", seq_len(n)), paste("Y", 1:p, sep = ":")))
dimnames(Z)

# the same as
# dimnames(Z)$Y <- list(paste0("i", seq_len(n)), paste("Y", 1:p, sep = ":"))
# dimnames(Z)


# a dataset from a  conditional censored Gaussian graphical model
n <- 100L
p <- 3L
q <- 2
b0 <- runif(p)
B <- matrix(runif(q * p), nrow = q, ncol = p)
X <- matrix(rnorm(n * q), nrow = n, ncol = q)
Z <- rcggm(n = n, b0 = b0, X = X, B = B, probl = 0.05, probr = 0.05)
dimnames(Z)

dimnames(Z) <- list(Y = list(NULL, paste("Y", 1:p, sep = ":")), 
                    X = list(NULL, paste("X", 1:q, sep = ":")))
dimnames(Z)

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