Usage

group_mean_center(data, group.var, vars, grand.init = FALSE)

Arguments

data	Data frame of individual observations across multiple groups.
group.var	Character string name of the grouping variable.
vars	Vector of numeric variable names to be centered.
grand.init	Is initial grand mean centering to each variable applied (default FALSE)?

Value

Data frame with group means and variables centered around group means.

Examples

set.seed(234)
n1 <- 3 # groups
n2 <- 3 # observations per groups
dat <- data.frame(
  group = rep(c(LETTERS[1:n1]), each = n2),
  x1 = sample(1:5, n1 * n2, replace = TRUE),
  x2 = sample(1:5, n1 * n2, replace = TRUE),
  x3 = sample(1:5, n1 * n2, replace = TRUE)
)

group_mean_center(
  data = dat, group.var = "group",
  vars = c("x1", "x2", "x3")
