ultrapolaRplot

Description

The ultrapolaRplot library for R is designed for plotting traced ultrasound tongue imaging data according to a polar coordinate system. There is currently support for plotting means and standard deviations of each category's trace; SSANOVA could be implemented as well. The origin of the polar coordinates may be defined manually or automatically determined based on different algorithms. Currently ultrapolaRplot supports ultrasound tongue imaging trace data from UltraTrace (<https://github.com/SwatPhonLab/UltraTrace>). UltraTrace is capable of importing data from Articulate Instruments AAA.

Examples

library(ultrapolaRplot)
filepath <- system.file("extdata", package = "ultrapolaRplot")
rawTraces <- loadTraces(filepath, categoriesAll = c("o", "i"))
polarTraces <- makeTracesPolar(rawTraces, origin.algorithm = "BottomMean")
plotTraces(rawTraces, polarTraces)
