#In-class experiment: creation of a new database
#Open Excel
#Create a database:
#- n statistical units = number of in-class students
#- 4 variables : k1= student�s ID; K2=student�s weight (kg); K3=student�s height (cm); K4=sex.
#Save your database in .csv (I call it wh)
#Open R and check the database structure
#Comment the variable�s nature
#Plot your data and comment
getwd()
#change your directory (if necessary)
getwd()
wh=read.csv("wh.csv2") #our in-class pcs don't use csv2, but csv
attach(wh)
View(wh)
str(wh)
plot(weight,height)
