plot(log(Time) ~ log(Distance), data=progression)
library(lattice)
xyplot(log(Time) ~ log(Distance), data=progression, type=c("p","r"))
xyplot(log(Time) ~ log(Distance), data=progression,
       type=c("p","smooth"))
res <- resid(lm(log(Time) ~ log(Distance), data=progression))
plot(res ~ log(Distance), data=progression,
     ylab="Residuals from regression line on log scales")
