elasticband

This data frame contains the following columns:

stretch

the amount by which the elastic band was stretched

distance

the distance traveled

Examples

# NOT RUN {
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")
