QUESTION
I am trying to write a .csv file that appends the important information from the summary of a glmer analysis (from the package lme4
).
I have been able to isolate the coefficients, AIC, and random effects , but I have not been able to isolate the scaled residuals (Min, 1Q, Median, 3Q, Max).
I have tried using $residuals, but I get a very long output, not the information shown in the summary.
...ANSWER

vignette.
QUESTION
To ease reproducibility, I am using the goats
data set from the ResourceSelection
package which has spatial data for used (STATUS == 1
) and 'available' (STATUS == 0
) GPS locations of mountain goats. ID
is for individual (n = 10) and ELEVATION, ... , TASP
are attributes of the points.

ANSWER
Answered 2019-Mar-13 at 22:11After I'd suggested using modelr
, I went ahead without it. Like I said above, your function SeasonalMods
doesn't know that Season
is a column in the data frame that it takes as an argument, so you'll get errors that it's undefined. One way to do this instead is to add a second argument to the function to take the season. Since you're nesting your data, it's easy now to pass the data and season to your modeling function. I'm using map2
because the columns data
and Season
are the same length.
QUESTION
I have a big data set and I want to choose randomly subsets (randomly_live) from it and then run a model (logistic regression) in R. So I want to run 100 logistic regressions to count how many times coefficients were with positive sign, haw many times they were significant and show the best model by Hosmer-Lemeshow criteria.
I think it's possible to make it by loop, but I feel really confused with that.
This is a piece of code that I have for one iteration

QUESTION
I want to sort the output of sessionInfo()
. I tried doing it using lapply()
but I am missing quite a few things.
For instance, when I tried this command:
