Functions in nullabor

Name Description
null_gen Computing th distance for the null plots
null_permute Generate null data by permuting a variable.
resid_sigma Residuals simulated by a normal model, with specified sigma
null_lm Generate null data with null residuals from a model.
rorschach The Rorschach protocol.
resid_boot Bootstrap residuals.
lineup The line-up protocol.
reg_dist Distance based on the regression parameters
null_dist Generate null data with a specific distribution.
electoral Polls and election results from the 2012 US Election
null_ts Generate null data by simulating from a time series model.
find_plot_data Find plot data. If data is not specified, this function will attempt to find the data corresponding to the last ggplot2 created or displayed. This will work in most situations where you are creating the plot and immediately displaying it, but may not work in other situations. In those cases, please specify the data explicitly.
uni_dist Distance for univariate data
visual_power Power calculations.
wasps Wasp gene expression data.
opt_bin_diff Finds the number of bins in x and y direction which gives the maximum binned distance.
resid_pboot Parametric bootstrap residuals.
lal Los Angeles Lakers play-by-play data.
resid_rotate Rotation residuals.
pvisual P-value calculations.
sep_dist Distance based on separation of clusters
turk_results Sample turk results
decrypt Use decrypt to reveal the position of the real data.
distplot Plotting the distribution of the distance measure
distmet Empirical distribution of the distance
calc_diff Calculating the difference between true plot and the null plot with the maximum distance.
aud Conversion rate of 1 Australian Doller (AUD) to 1 US Dollar
add_true Add true data into data frame containing null data sets.
bin_dist Binned Distance
calc_mean_dist Calculating the mean distances of each plot in the lineup.
box_dist Distance based on side by side Boxplots
