This package includes a set of convenience functions for data preparation and summarization.
elements counts the number of elements in a data.frame, matrix, or vector.
fix.missing takes in a vector and a missing code (e.g., "-99", "-999") and returns a vector with missing items coded as NA.
mode returns the modal value of a vector.
percents turns a vector of proportions into percentages.
rescale01 rescales a vector so its elements fall between 0 and 1. rescale0100 does the same but for a range from 0 to 100.
s takes in a data frame and returns several statistics: mean, median, standard deviation, mean absolute deviation, and the interquartile range.
