LME model error

Hi I am trying to run a linear mixed effect model using the LME4 package.

I am getting the following error:

Error in initializePtr() :
function 'cholmod_factor_ldetA' not provided by package 'Matrix'

I tried to install "Matrix" package. But Matrix package is failing to install. R is restarting automatically.

Please anyone knows the solution.


Hi, welcome to the forum.

I think we need to see your code and some sample data. See
FAQ Asking Questions

A handy way to supply some sample data is the dput() function. In the case of a large dataset something like dput(head(mydata, 100)) should supply the data we need. Just do dput(mydata) where mydata is your data. Copy the output and paste it here between


Why ? You should address that...
