Grouping by interval
Hello,
I have a dataframe of say 20 lines with one line per individual. I want to group these 20 individuals
by length class (eg. of 5cm) and get the mean value of all the other variables (eg VarA and VarB) for each length class
My dataframe is as follow:
Length <- 10:30
VarA <- seq(1000,1200,10)
VarB <- seq(500,700,10)
Data <- cbind(Length,VarA,VarB)
And I want to get something
