Hi all, trying to run a linear mixed-effects model in R. Getting a ton of
errors when trying to install the lme4 package (see below). I thought it
was because my version of R was old, I just updated it, same exact problem,
plus tried the install on the 32 and 64 bit versions. Any help appreciated.

Thank you. That's what I was looking for.
I am wondering what does the documentation means by (first) than?
match {base}
match returns a vector of the positions of (first) matches of its
first argument in its second.

Dear Witold,
as a first hint: read posting guide please! People are answering in their free
time, so please try to be polite!
For your first problem: what are you expecting? You have a dataset where most
of the values is missing, the others all 0's most of the time, and some Inf
values as well
I suppose there may be an error of sorts, but have you considered
the fact that solving the error might not gain you admittance into
heaven? Look at the RHS of the model:

variable.
