CIRCUIT: Circuit Design Lifetime

In PASWR2: Probability and Statistics with R, Second Edition

Description

Results from an accelerated life test used to estimate the lifetime of four different circuit designs (lifetimes in thousands of hours)

Usage

CIRCUIT

Format

A data frame with 26 observations on the following 2 variables:

• lifetime (lifetimes in thousands of hours)

• design (a factor with levels DesignI and DesignII)

Examples

# ggplot2 approach
ggplot(data = CIRCUIT, aes(x = design, y = lifetime, fill = design)) + geom_boxplot() + 
labs(x = "", y = "Lifetime in thousands of hours") + guides(fill = "none") + 
scale_fill_brewer()
ggplot(data = CIRCUIT, aes(x = design, y = lifetime, fill = design)) + geom_violin() + 
labs(x = "", y = "Lifetime in thousands of hours") + guides(fill = "none") + 
scale_fill_brewer()
# Reorder the boxplots by medians
ggplot(data = CIRCUIT, aes(x = reorder(design, lifetime, FUN = median),  lifetime, 
fill = design)) + geom_boxplot() + labs(x = "", y = "Lifetime in thousands of hours") + 
guides(fill = "none") + scale_fill_brewer()
