问题
I was able to download the package "LMERConvenienceFunctions"
The downloaded binary packages are in
/var/folders/2p/3h5yk1gx4fs1gd8gtdbhdd900000gn/T//RtmpHvJyRm/downloaded_packages
However when I try to call it using:
library(LMERConvenienceFunctions)
I get the following error:
Error : .onLoad failed in loadNamespace() for 'rgl', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object'/Library/Frameworks/R.framework/Versions/3.2/Resources/library/rgl/libs/rgl.so': dlopen(/Library/Frameworks/R.framework/Versions/3.2/Resources/library/rgl/libs/rgl.so, 6):
Library not loaded: /opt/X11/lib/libGLU.1.dylib
Referenced from: /Library/Frameworks/R.framework/Versions/3.2/Resources/library/rgl/libs/rgl.so
Reason: image not found
Error: package or namespace load failed for ‘LMERConvenienceFunctions’
Does anyone have any suggestions?
Thanks!
回答1:
It seems like you have tried to install the "LMERConvenienceFunctions" package without also downloading it's dependencies? Running
install.packages("LMERConvenienceFunctions")
and then just using library(LMERConvenienceFunctions) worked for me in this case. If this still doesn't work, try manually installing rgl

My issue turned out to be that I didn't have XQuartz installed. It can be downloaded here: http://www.xquartz.org/
After installing it, rgl began to work, and then LMERConvenienceFunctions finally started working as well. The whole process took a few tweaks so I'm pasting the entire code below. Note that this is after installing XQuartz.
install.packages("LMERConvenienceFunctions")
install.packages("devtools") #not sure if this is necessary, but doing this before rgl was recommended on another answer on here#
library(devtools)
install.packages("rgl")
rgl.useNULL=TRUE #little thing I had to do even after installing XQuartz#
library(rgl)
library(LMERConvenienceFunctions)
