Extract the fixed-effects estimates
## S3 method for class 'merMod' fixef(object, add.dropped=FALSE, ...)
object |
any fitted model object from which fixed effects estimates can be extracted. |
add.dropped |
for models with rank-deficient design
matrix, reconstitute the full-length parameter vector by
adding |

optional additional arguments. Currently none are used in any methods. |
Extract the estimates of the fixed-effects parameters from a fitted model.
a named, numeric vector of fixed-effects estimates.
fixef(lmer(Reaction ~ Days + (1|Subject) + (0+Days|Subject), sleepstudy))
fm2 <- lmer(Reaction ~ Days + Days2 + (1|Subject),
data=transform(sleepstudy,Days2=Days))
fixef(fm2,add.dropped=TRUE)
## first two parameters are the same ...
