Electrical Resistance of Kiwi Fruit

Description

Data are from a study that examined how the electrical resistance of a slab of kiwifruit changed with the apparent juice content.

Usage

fruitohms

Format

This data frame contains the following columns:

juice

apparent juice content (percent)

ohms

electrical resistance (in ohms)

Examples

plot(ohms ~ juice, xlab="Apparent juice content (%)",ylab="Resistance (ohms)", data=fruitohms)
lines(lowess(fruitohms$juice, fruitohms$ohms), lwd=2)
pause()require(splines)
attach(fruitohms)
plot(ohms ~ juice, cex=0.8, xlab="Apparent juice content (%)",
     ylab="Resistance (ohms)", type="n")
fruit.lmb4 <- lm(ohms ~ bs(juice,4))
ord <- order(juice)
lines(juice[ord], fitted(fruit.lmb4)[ord], lwd=2)
ci <- predict(fruit.lmb4, interval="confidence")
lines(juice[ord], ci[ord,"lwr"])
