Methods (by class)
-
bru_index(bru_like)
: Extract the index vector for the predictor vector for abru_obs()
sub-model. The indices are relative to the sub-model, and need to be appropriately offset to be used in the full model predictor. -
bru_index(bru)
: Extract the index vector for "APredictor" for one or more specified observationbru_obs()
sub-models. Accepts any combination oftag
andwhat
.
Examples
fit <- bru(
~ 0 + x,
bru_obs(
y ~ .,
data = data.frame(x = 1:3, y = 1:3 + rnorm(3)),
tag = "A"
),
bru_obs(
y ~ .,
data = data.frame(x = 1:4, y = c(NA, NA, 3:4) + rnorm(4)),
tag = "B"
)
)
bru_index(fit)
bru_index(fit, "A")
bru_index(fit, "B")
bru_index(fit, c("B", "A"))
bru_index(fit, what = "missing")
