Hello,
I have installed the nlme package, but every time I try to use the
function "summary.lme,"
How did you "try to use it"?
I get a message that the function cannot be
found.
If it says it cannot be found, then you quite possibly forgot to load
the "lme4" package. Try:
require(lme4)
If you have an object "obj1" of class "lme" then typing:
summary(obj1)
will be dispatched by the R interpreter to apply the summary.lme
function to that object. Functions like summary() are called
"generic". They are really underneath the hood actually a collection
of functions. For summary you can see the ones that are currently
loaded by typing:
methods(summary)
I've tried to install the package several times and have
re-started R several times, but to no avail. I have also loaded the
lme4 package, in case that makes a difference. I'm using R on a brand
new Mac.
Thank you!
