summarizeFactors
for a function that
handles non-numeric variables.). It calculates the
quantiles for each variable, as well as the mean,
standard deviation, and variance, and then packs those
results into a matrix. The main benefits from this
compared to R's default summary are 1) more summary
information is returned for each variable (dispersion),
2) the results are returned in a matrix that is easy to
use in further analysis, 3) the columns in the output are
alphabetized. To prevent alphabetization, use alphaSort =
FALSE.summarizeNumerics(dat, alphaSort = TRUE, sumstat = TRUE,
digits = max(3, getOption("digits") - 3))
