sub-.gmd: Subset Operator for Gaussian Mixture Data

In astamm/game: GAussian Mixture Embedding

Description

Subset Operator for Gaussian Mixture Data

Usage

## S3 method for class 'gmd'
x[i, j, ..., drop = TRUE]

Arguments

x	An object of class gmd.
i	A valid expression giving instructions for subsetting observations.
j	Unused.
...	Unused.
drop	Unused.

Value

An object of the same class as the input object with only the subset of observations identified by the expression in argument i.

Examples

N <- 100
M <- 4
w <- matrix(runif(N * M), N, M)
w <- w / rowSums(w)
s <- tidyr::crossing(
  observation = paste0("O", 1:N),
  component = paste0("C", 1:M)
) %>%
dplyr::mutate(mixing = as.numeric(t(w)))
d <- tibble::tibble(
  component = paste0("C", 1:M),
  mean = numeric(M),
  precision = 1:M
)
x <- gmd(s, d)
x[2]
x[2:4]
x[c(1, 3)]
x[-1]
x["O2"]
x[c("O1", "O3")]
