vis_guess visualises the class of every single individual cell in a dataframe and displays it as ggplot object, similar to vis_dat. Cells are coloured according to what class they are and whether the values are missing. vis_guess estimates the class of individual elements using readr::guess_parser. It may be currently slow on larger datasets.

vis_guess(x, palette = "default")



a data.frame


character "default", "qual" or "cb_safe". "default" (the default) provides the stock ggplot scale for separating the colours. "qual" uses an experimental qualitative colour scheme for providing distinct colours for each Type. "cb_safe" is a set of colours that are appropriate for those with colourblindness. "qual" and "cb_safe" are drawn from


ggplot2 object displaying the guess of the type of values in the data frame and the position of any missing values.
