R language: Random sampling (sample function)

If you want to randomly extract a number from a set of datasets, you can do so with the sample function, which shows the following code:

Forehead<-c (249,189,128,111,184,233,313,120,151,196,135,157,145,218) sample (forehead,1) # 1 to randomly extract a number from the forehead data set

Similarly, randomly extracting two or three numbers from a dataset will change 1 to 2 or 3:

Sample (forehead,2) sample (forehead,3)

The results are as follows:
