The oddsratio function simply computes a point estimate and confidence interval for an odds ratio.

Usage

oddsratio(x, y = NULL, conf.level = .95, digits=2)

Arguments

x
x can be either a table (then y can be NULL) or a factor.
y
If x is a factor, y also has to be a factor; x and y are then used to create the crosstable.
conf.level
The confidence level of the confidence interval.
digits
Number of digits to round output to

Value

The oddsratio function returns an object with the input and output. The oddsratio function returns an object with the input and output.

Examples

Run this code
### Generate two factor vectors
treatment <- factor(c(rep(0, 33), rep(1, 45), rep(0, 63), rep(1, 21)),
                    levels=c(0,1), labels=c("no", "yes"));
survival <- factor(c(rep(0, 78), rep(1, 84)),
                   levels=c(0, 1), labels=c("no", "yes"));

### Compute and display odds ratio
oddsratio(treatment, survival);

### Or present a table
oddsratio(table(treatment, survival));
