# Fits von Mises kernel density to time-of-day data.

### Description

Fits von Mises kernel density to time-of-day data. Intended primarily for internal use: input checking is minimal.

### Usage

1 | ```
densityFit(x, grid, bw)
``` |

### Arguments

`x` |
a vector of times of observations in |

`grid` |
a vector of times in |

`bw` |
bandwidth, the concentration parameter for the von Mises kernel: smaller values result in smoother curves. |

### Value

Returns a vector of densities corresponding to the times in grid.

### Author(s)

C code written by Mike Meredith.

### See Also

`getBandWidth`

for appropriate bandwidth.

### Examples

1 2 3 4 5 6 | ```
# Get example data:
data(simulatedData)
densityFit(tigerObs, c(0, pi/2, pi, 3*pi/2, 2*pi), 50)
# Densities at 6am and 6pm are fairly high, at midnight and midday, tiny.
# A crepuscular species!
