Examples

print("Example 1.8.1")attach(elasticband)     # R now knows where to find stretch and distance
plot(stretch, distance) # Alternative: plot(distance ~ stretch)
detach(elasticband)
pause()print("Output of Data Frames - Example 12.3.2")write(t(elasticband),file="bands.txt",ncol=2)sink("bands2.txt")
elasticband   # NB: No output on screen
sink()print("Lists - Example 12.7")elastic.lm <- lm(distance ~ stretch, data=elasticband)
