ADDED: umx_cont_2_quantiles(x, nlevels = )
ADDED: umx_factor alias to umxFactor
FIXED: plot(resid = "none") was not suppressing plotting residuals
IMPROVED: umxFactor now handles dataframes and allows non-ordered output
IMPROVED: umx_CI more flexible, now allows removing CIs
- Old code will break: replace "add" with "which"
IMPROVED: umx_time handling of no input arguments
IMPROVED: umx_pb_note better feedback and setup
IMPROVED: loadings() generic
CHANGE: umxModify - if free is a string, it will be used as input and the found paths will be freed.
CHANGE: umxModify - show summary as well when comparison = TRUE
CHANGE: plot defaults for std and showFixed changed h/t @MikeNeale
CHANGE: umx_scale_wide_twin_data argument names for consistency: "suffix" "data"
CHANGE: umx_residualize ditto.
UPDATE: "Read me" file.
