I have the following data structure: n=5 mydata <- data.frame(id=1:n, x=rnorm(n), y=rnorm(n), id=1:n, x=rnorm(n), y=rnorm(n)) print(mydata)
producing the following represention id x y id.1 x.1 y.1 1 1 0.5326855 -2.07633703 1 0.7930274 -1.0530558 2 2 0.7888909 0.63354693 2 0.5908323 -1.3543282 3 3 0.5350803 -0.20108931 3 2.5079242 -0.4657274 4 4 -1.3041960 -0.25195129 4 1.6294046 -1.4094830 5 5 0.3109767 -0.02305981 5 0.5183756 1.3084776 however I need to transform this data into this form: id x y 1 1 0.5326855 -2.07633703 2 2 0.7888909 0.63354693 3 3 0.5350803 -0.20108931 4 4 -1.3041960 -0.25195129 5 5 0.3109767 -0.02305981 6 1 0.7930274 -1.0530558 7 2 0.5908323 -1.3543282 8 3 2.5079242 -0.4657274 9 4 1.6294046 -1.4094830 10 5 0.5183756 1.3084776 what is the simplest way to do that?
