figure_extractDetectedPoints: Extracts data points from a detected image.

Description

Extracts raw X and Y data from the points detected in a scatter-plot figure.

Usage

figure_extractDetectedPoints(
  aDetectedPlot,
  xAxis = NULL,
  yAxis = NULL,
  X_min = NULL,
  X_max = NULL,
  Y_min = NULL,
  Y_max = NULL,
  summarize = TRUE
)

Arguments

aDetectedPlot

A binary figure image with detected points (an EBImage object). See: figure_detectAllPoints

xAxis

A binary figure image with detected X-axis (an EBImage object). See: figure_detectAxis.

yAxis

A binary figure image with detected Y-axis (an EBImage object). See: figure_detectAxis.

X_min

The minimum value of X reported on the figure X-axis.

X_max

The maximum value of X reported on the figure X-axis.

Y_min

The minimum value of Y reported on the figure Y-axis.

Y_max

The maximum value of Y reported on the figure Y-axis.

summarize

When TRUE returns a summary of the regression parameters (intercept + slope * X), R-squared, Pearson's product moment correlation coefficient (r), and its variance (var_r) and sample size (N).

Value

A data frame with the extracted X and Y values.
