Usage

project_points_onto_line(points, line_start, line_end)

Arguments

points

a dataframe, matrix, or embeddings object in which each row represents the coordinates of a point to be projected onto the line

line_start

a vector of representing the coordinates of the line's start

line_end

a vector representing the coordinates of the line's end

Details

project_points_onto_line calculated the projections of a group of points onto a line defined by two end points. It is useful for graphing the positions of embeddings with respect to an anchored vector.

Examples

emotion_words <- c("happy", "sad", "scared", "angry", "anxious", "grateful")
emotion_embeddings <- predict(glove_twitter_25d, emotion_words)
#> Warning: 1 items in `newdata` are not present in the embeddings object.
emotion_embeddings_2d <- reduce_dimensionality(emotion_embeddings, 2)

# project points
happy_vec_2d <- predict(emotion_embeddings_2d, "happy")
sad_vec_2d <- predict(emotion_embeddings_2d, "sad")
emotional_projections <- emotion_embeddings_2d |>
  project_points_onto_line(happy_vec_2d, sad_vec_2d)
