## Interactively identify points in plot

### Description

Interactively identify points in x,y plot.

### Usage

```
idPts(dat1,dat2=NULL,ptsize=0.5,xmin=NULL,xmax=NULL,ymin=NULL,ymax=NULL,
logx=F,logy=F,plotype=1,annotate=1,iso=F,output=1,verbose=T)
```

### Arguments

`dat1` |
Data frame with one, two or three columns. If one column, dat2 must also be specified. If three columns, the data frame is assumed to represent a stratigraphic series, and the first column should be depth, height or time. |

`dat2` |
Data frame with one column. |

`ptsize` |
Size of plotted points. |

`xmin` |
Minimum x-value (column 1) to plot |

`xmax` |
Maximum x-value (column 1) to plot |

`ymin` |
Minimum y-value (column 2) to plot |

`ymax` |
Maximum y-value (column 2) to plot |

`logx` |
Plot x-axis using logarithmic scaling? (T or F) |

`logy` |
Plot y-axis using logarithmic scaling? (T or F) |

`plotype` |
Type of plot to generate: 1= points and lines, 2 = points, 3 = lines |

`annotate` |
Annotate plot with text indicating coordinates?: 0=none, 1=annotate above point, 2=annotate below point |

`iso` |
Isolate data between minimum and maximum x-values selected? (T or F) This option requires that both dat1 and dat2 have one column each, or if dat2 is null, dat1 has only two columns. |

`output` |
Return identified points as a data frame? (0) no, (1) return x and y, (2) return index, x and y. If dat1 contains three columns, option 2 will return index, location, x and y. |

`verbose` |
Verbose output? (T or F) |
