Interactively identify points in plot

Interactively identify points in x,y plot.

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)

`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)
