Hi,
I wish to extract a subset of the information of given by
summary(lmer.object) as a dataframe. In particular, I wish to extract
just a table listing the Estimate, Std Error, and t-values rounded to
3 decimal places. I have learned how to extract the coefficients with
"round(fixef(lmer.object),3)" and the standard errors with
"round(sqrt(diag(vcov(a.lmer))),3)"
but I do not know how to extract the t-values; the extractor methods
do not seem to help in this regard. I inspected the structure of the
summary with "str(summary(lmer.object))" but unfortunately I am new to
R and didn't find this very enlightening. Here is an example of the
dataframe I would like to produce:
Factor Estimate Std. Err t
FixedFac1 0.091 0.140 0.651
FixedFac2 0.054 0.012 4.461
FixedFac3 -0.078 0.021 -3.664
Cheers,
Barry.
