v2.0

This release includes significant changes to function names, function parameters, and contents. Please see the manual.pdf for specific changes. Below is a brief summary of these changes.

• Primary function RAR_ExCosine() from v1.0 is now changed to RAR()
• Plotting functions are separate from primary functions. For example, use RAR_plot() to plot output from RAR().
• Main functions now handle datasets with multiple subjects. For example, by specifying id_column in RAR(df, act_column, time_column, transform = c("antilogit", "arctan", "hill"), id_column=id) where id is the ID column name of df.
• Plotting functions also can visualize output from multiple subjects by specifying which id_vals to visualize. For example RAR_plot(rar_output, predicted=c(TRUE, FALSE), id_vals=c("1", "29"), where "1" and "29" are specific ID values within id_column = id.
