• Package: psych

• Purpose: Descriptive statistics and exploratory data analysis.

• General Class: Descriptive statistics.

• Required Argument(s):

• x: The data frame or matrix containing the variables to describe.

• Notable Optional Arguments:

• trim: Trims a percentage of data from both ends before computing statistics.

• quant: Determines which quantiles to calculate (e.g., quant=c(0.25, 0.75) for quartiles).
