Hi, I am currently using R for a university project for the first time and I am trying to plot rank abundance curves for 3 habitats. On the final one it gives 20 warnings and will not show any line. on the rank abundance plot.

1: In dpois(y, mu, log = TRUE) : non-integer x = 108.875000

2: In dpois(y, mu, log = TRUE) : non-integer x = 87.750000

3: In dpois(y, mu, log = TRUE) : non-integer x = 51.625000

4: In dpois(y, mu, log = TRUE) : non-integer x = 38.250000

5: In dpois(y, mu, log = TRUE) : non-integer x = 9.875000

6: In dpois(y, mu, log = TRUE) : non-integer x = 5.750000

7: In dpois(y, mu, log = TRUE) : non-integer x = 4.875000

8: In dpois(y, mu, log = TRUE) : non-integer x = 3.750000

9: In dpois(y, mu, log = TRUE) : non-integer x = 3.375000

10: In dpois(y, mu, log = TRUE) : non-integer x = 2.750000

11: In dpois(y, mu, log = TRUE) : non-integer x = 2.500000

12: In dpois(y, mu, log = TRUE) : non-integer x = 2.500000

13: In dpois(y, mu, log = TRUE) : non-integer x = 2.250000

14: In dpois(y, mu, log = TRUE) : non-integer x = 1.375000

15: In dpois(y, mu, log = TRUE) : non-integer x = 1.375000

16: In dpois(y, mu, log = TRUE) : non-integer x = 0.625000

17: In dpois(y, mu, log = TRUE) : non-integer x = 0.250000

18: In dpois(y, mu, log = TRUE) : non-integer x = 0.125000

19: In dpois(y, mu, log = TRUE) : non-integer x = 0.125000

20: In dpois(y, mu, log = TRUE) : non-integer x = 0.125000

When i try to research the warnings it mostly shows questions related to GLM not biodiversity analysis. How do I get rid of the warnings?
