Exploratory Data Anaalysis

Function that produces a histogram, density plot, boxplot, and Q-Q plot.

EDA(x, trim = 0.05)

Arguments

• x: numeric vector. NAs and Infs are allowed but will be removed.
• trim: fraction (between 0 and 0.5, inclusive) of values to be trimmed from each end of the ordered data. If trim = 0.5, the result is the median.

Returns

Note

Requires package e1071.
