Unable to properly install lme4

[sharon_r]

Hi all

I am unable to install lme4 on my Mac (> install.packages("lme4")). I get:

trying URL 'https://cran.rstudio.com/bin/macosx/el-capitan/contrib/3.6/lme4_1.1-21.tgz'

Content type 'application/x-gzip' length 7809491 bytes (7.4 MB)

==================================================

downloaded 7.4 MB

The downloaded binary packages are in

/var/folders/bd/b5bgq2rj1_n25ch1ff4przyh0000gn/T//RtmpDA7auj/downloaded_packages

Then, I get an error message (could not find function "glmer").

Please help me to resolve this issue. Your help is much appreciated.

Have you loaded the package before calling glmer?
library(lme4)
