idPts {astrochron}R Documentation

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)
