Extract SE of Fixed Effects
This function extracts the standard errors (SE) of the fixed effects of
a mixed model fit with coxme, glmer, lmer,
lmerModLmerTest, and lmekin and adds the appropriate labels.
extractSE(mod, ...) ## S3 method for class 'coxme' extractSE(mod, ...) ## S3 method for class 'lmekin' extractSE(mod, ...) ## S3 method for class 'mer' extractSE(mod, ...) ## S3 method for class 'merMod' extractSE(mod, ...) ## S3 method for class 'lmerModLmerTest' extractSE(mod, ...)
mod |

additional arguments passed to the function. |
These extractor functions use vcov.coxme, vcov.lmekin,
vcov.mer, and vcov.merMod. Some of these functions are
called by modavg and modavgShrink, depending on the
class of the objects.
Returns the SE's of the fixed effects with the appropriate labels for each.
