I am using the R package lattice to make a level plot. I am getting funny horizontal white lines across my panels:
I do not understand why I am getting these. My H0a values are spaced very closely. There are no missing values either. For example in the bottom right panel I have at H0b=1.0
y H0b H0a
[1,] 1.021897 1 0.05
[2,] 1.043798 1 0.10
[3,] 1.065699 1 0.15
[4,] 1.087600 1 0.20
[5,] 1.109500 1 0.25
[6,] 1.131400 1 0.30
[7,] 1.153299 1 0.35
[8,] 1.175198 1 0.40
[9,] 1.197095 1 0.45
[10,] 1.218991 1 0.50
[11,] 1.240886 1 0.55
[12,] 1.262778 1 0.60
[13,] 1.284667 1 0.65
[14,] 1.306551 1 0.70
[15,] 1.328428 1 0.75
[16,] 1.350292 1 0.80
[17,] 1.372130 1 0.85
[18,] 1.393909 1 0.90
[19,] 1.415481 1 0.95
[20,] 1.433730 1 1.00
Even when I set H0a at fine gradations, this problem does not go away
was hoping to get some help?
