# Format P-values for Functions in the tab Package

### Description

This function formats p-values for tables generated by the functions in the package tab. It handles rounding and presentation of p-values.

### Usage

1 2 |

### Arguments

`p` |
Numeric value or vector of p-values. |

`decimals` |
Number of decimal places for p-values. If a vector is provided rather than a single value, number of decimal places will depend on what range the p-value lies in. See cuts. |

`cuts` |
Cut-point(s) to control number of decimal places used for p-values. For example, by default cuts is 0.1 and decimals is c(2,3). This means that p-values in the range [0.1, 1] will be printed to two decimal places, while p-values in the range [0, 0.1) will be printed to three decimal places. |

`lowerbound` |
Controls cut-point at which p-values are no longer printed as their value, but rather <lowerbound. For example, by default lowerbound is 0.001. Under this setting, p-values less than 0.001 are printed as <0.001. |

`leading0` |
If TRUE, p-values are printed with 0 before decimal place; if FALSE, the leading 0 is omitted. |

`avoid1` |
If TRUE, p-values rounded to 1 are not printed as 1, but as >0.99 (or similarly depending on values for decimals and cuts). |

# Generate vector of numeric p-values
set.seed(123)
p <- c(runif(n = 5, min = 0, max = 1), 1, 0, 4e-7, 0.009)
# Round to nearest 2 decimals for p in (0.01, 1] and 3 decimals for p < 0.01
pvals <- formatp(p = p)
# Use 2 decimal places, a lower bound of 0.01, and omit the leading 0.
pvals <- formatp(p = p, decimals = 2, lowerbound = 0.01, leading0 = FALSE)
