错误:找不到功能"lmer"

Question

我在Mac OS X 10_9_5上运行RStudio版本0.98.1062.我加载了包"lattice"和"nlme",并没有收到错误消息.我读了一些数据并使用了一些简单的函数.但是当我尝试使用lmer时,我得到错误:"找不到函数"lmer"".这是我做的:

> library("lattice", lib.loc="/Library/Frameworks/R.framework/Versions/3.1/Resources/library")
> library("nlme", lib.loc="/Library/Frameworks/R.framework/Versions/3.1/Resources/library")
> dat = read.table("StatsPrepDAT2005_2010.txt", T)
> table(dat$language, dat$data_time)
       2005 2010
  LW     37   69
  Wrlp   33   62
> dat.lmer = lmer(casevowela ~ language + data_time + (1|speaker) + (1|story), family= "binomial", data= dat)
Error: could not find function "lmer"

Answer 1

lmer由...提供lme4.你需要加载它:

library(lme4)
