is_point_in_path: Check if a point is contained in a polygon

In jspaezp/flowhelperrr: Helps you analyze flow cytometry data using data frames

Description

based on: https://en.wikipedia.org/wiki/Even

Usage

is_point_in_path(x, y, poly)

is_point_df_in_path(point_df, poly_df)

Arguments

x	The x coordinates of point.
y	The y coordinates of point.
poly	a list of numeric vectors defining the polygon list(c(x, y), c(x, y), ...) or a data.frame data.frame(x = c(0,0,1), y = c(0,1,1))
point_df	a data.frame defining the points to check, column names are expected
poly_df	a data.frame defining a polygon, column are expected

Functions

• is_point_df_in_path: Find wether points are inside a polygon, defining both as data frames with matching names

Examples

poly_selection <- data.frame(
  Petal.Length = c(2, 4, 6),
  Sepal.Width = c(2, 4, 2)
)

dplyr::mutate(
  iris,
  point_in_poly = is_point_in_path(
    Petal.Length,
    Sepal.Width,
    poly_selection
  )
)
