In metagear: Comprehensive Research Synthesis Tools for Systematic Reviews and Meta-Analysis

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.
