Small example of R language---Simple data analysis and drawing

There are currently data on age and height ( fictional data)for children (males), who are interested in the relationship between elevated distribution and weight and age.

Age (years)	Weight (kg)	Age (years)	Weight (kg)
4	95	6	116
4	97	7	120
5	106	7	121
5	108	8	126
6	114	8	125

Use the function C () to enter the child's age and height data in vector form. Then, use some built-in functions to get the mean and standard deviation of height, as well as the correlation of age and weight.

> Age <-C (4,4,5,5,6,6,7,7,8,8) > Height <-C (95,97,106,108,114,116,120,121,126,125) > mean (height) [1] 112.8> SD (height) [1] 11.00303> cor (age,height) [1] 0.9822442> plot (age,height)
