REquantile: Identify group level associated with RE quantile

Description

For a user specified quantile (or quantiles) of the random effect terms in a merMod object. This allows the user to easily identify the observation associated with the nth percentile effect.

Usage

REquantile(merMod, quantile, groupFctr, term = "(Intercept)")

Value

a vector of the level of the random effect grouping term that corresponds to each quantile

Arguments

merMod

a merMod object with one or more random effect levels

quantile

a numeric vector with values between 0 and 100 for quantiles

groupFctr

a character of the name of the random effect grouping factor to extract quantiles from

term

a character of the random effect to extract for the grouping factor specified. Default is the intercept.

Examples

# \donttest{
fm1 <- lmer(Reaction ~ Days + (Days | Subject), sleepstudy)
REquantile(fm1, quantile = 0.25, groupFctr = "Subject")
REquantile(fm1, quantile = 0.25, groupFctr = "Subject", term = "Days")
# }
