## Tools for Sports Betting
This package contains tools and functions to help sports bettors make more money!
## Installation
You can install bettoR from [GitHub](https://github.com/a-i-sports/bettoR) with:
```{r installs, eval=FALSE}
# install.packages("devtools")
devtools::install_github("a-i-sports/bettoR")
```
## Examples
#### Implied Probability
Implied probabilities, or break-even win percentage, can easily be found with this function. Here is an example with given odds of -350 (US Odds), 180 (US Odds), 2.5 (Decimal Odds), 4.9 (Decimal Odds), 6-1 (Fractional Odds), 2/7 (Fractional Odds).
```{r}
implied_prob(-350, type = "us")
```
```{r}
implied_prob(180, type = "us")
```
```{r}
implied_prob(2.5, type = "dec")
```
```{r}
implied_prob(4.9, type = "dec")
```
```{r}
implied_prob(6/1, type = "frac")
```
```{r}
implied_prob(2/7, type = "frac")
```
#### Odds from Probabilities
Let's say you believe a bet has a 75% chance to cover, what would the price be? Using the implied odds function can give you the price based on your probability.
```{r}
implied_odds(0.75, type = "us")
```
```{r}
implied_odds(0.75, type = "frac")
```
```{r}
implied_odds(0.75, type = "dec")
```
```{r}
implied_odds(0.75, type = "all")
```
#### Converting Odds
Let's say you want to convert the American Odds you see on the screen (-175) to another type.
```{r}
convert_odds(-175)
```
#### Calculate Sportsbook's hold
Betting into a market is difficult enough as is but some sportsbooks skew the odds even more in their favor. (-110, -110) is the industry standard. The hold, or vig/juice, for this bet can be found like this:
```{r}
hold_calc(-110, -110)
```
Some sportsbooks in newly legalized states are taking advantage of bettors with lines (-125, -125)
```{r}
hold_calc(-125, -125)
```
The increase in juice for this is:
```{r}
(hold_calc(-125, -125) - hold_calc(-110, -110)) / hold_calc(-110, -110)
```
133% increase in price.
