R Dataset / Package DAAG / elasticband

On this R-data statistics page, you will find information about the elasticband data set which pertains to Elastic Band Data. The elasticband data set is found in the DAAG R package. You can load the elasticband data set in R by issuing the following command at the console data("elasticband"). This will load the data into a variable called elasticband. If R says the elasticband data set is not found, you can try installing the package by issuing this command install.packages("DAAG") and then attempt to reload the data with the library() command. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the elasticband R data set. The size of this file is about 70 bytes.

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)
