The original data contains scores of case/control group. The score is the number of risk alleles multiplied by the regression coefficient for SNP. So in the data, case samples have higher score than control samples.
ID disease Score 001 case 5.93 002 case 6.12 003 case 6.54 004 control 3.67 005 control 2.33 006 control 1.24
Now I grouping control samples in decile, and I want to calculate odds ratio for each decile. Finally output a plot like below. Can anyone please tell me how can I calculate this in R or other software?
