Add information for line-by-line visualization

This function adds columns to the dataset that adds a line ID, and changes columns with timestamps relative to the beginning of the line, so data can be visualized line-by-line. The participant column is also adjusted to create a Y-coordinate for each speaker. The line duration is set to 60 seconds by default.

Usage

add_lines(data, time_columns = c("begin", "end"), line_duration = 60000)

Arguments

data: dataset to divide into lines
time_columns: columns with timestamps that need to be adjusted to line-relative time
line_duration: length of line (in ms)

Value

data set with added columns: `line_id`, `line_participant`, and `line_column` for every column in `time_columns`

Details

This transformation can be done for multiple columns with time-stamped data. Use the `time_columns` argument to supply the names of one or more columns that should be transformed.
