idPts {astrochron} | R Documentation |
Interactively identify points in x,y plot.
idPts(dat1,dat2=NULL,ptsize=1,xmin=NULL,xmax=NULL,ymin=NULL,ymax=NULL,
logx=F,logy=F,plotype=1,annotate=1,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 |
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) |
