Save lme4-output to disc

The output of any lme4 analysis is saved in a memory saving manner.

Usage

save.lmer.effects(
  lmerObj,
  lmerObjRestrict = NULL,
  fileName,
  scipen = 6,
  standardized = FALSE,
  digits = 3,
  quick = FALSE
)

Arguments

lmerObj

An lme4 object to be saved.

lmerObjRestrict

Optional: a second (restricted) lme4 analysis output. Needs to be nested to the first one. Intended if model comparison should be saved likewise.

fileName

Name of the file for the output (without file extension).

scipen

Maximum number of decimal places before exponential notation is used.

standardized

Logical: Additionally print standardized coefficients to the output?

digits

Number of digits for printing standardized results

quick

Logical: Sometimes, default method for computing \(R^2\) by calling r.squaredGLMM is very time-consuming. Using quick = TRUE forces the function to choose an alternative method which, however, is not available when lmerTest is attached. If lmerTest is attached, no \(R^2\) is computed if quick = TRUE.

Value

No output is returned to console. Two files are created in the desired directory.

Examples

if (FALSE) { # \dontrun{
library(lme4)
### Example from the help page of lmer().
fm1 <- lmer(Reaction ~ Days + (Days | Subject), sleepstudy)
save.lmer.effects(fm1, fileName = tempfile())

### with model comparison
### specify a "null model" nested in the first one: no fixed effects, only intercept
fm0 <- lmer(Reaction ~ (Days | Subject), sleepstudy)
save.lmer.effects(lmerObj = fm1, lmerObjRestrict = fm0, fileName = tempfile())
} # }
