ENH/CLN: Integration with {broom}

[sinhrks]

• http://cran.r-project.org/web/packages/broom/index.html

Utilize {broom} as much if outputs data.frame which has enough information for plotting.

• aareg_tidiers
• anova_tidiers
• cch_tidiers
• confint_tidy
• coxph_tidiers
• cv.glmnet_tidiers
• felm_tidiers
• gam_tidiers
• glmnet_tidiers
• lme4_tidiers
• multcomp_tidiers
• nls_tidiers
• pyears_tidiers
• ridgelm_tidiers
• rlm_tidiers
• sexpfit_tidiers
• smooth.spline_tidiers
• sp_tidiers
• survfit_tidiers
• survreg_tidiers
• tidy.manova
• tidy.map
• tidy.TukeyHSD

Affects to backward compat

autoplot should not be affected. Column names output from fortify may be affected.

• kmeans_tidiers
• tidy.density
• tidy.spec

Unable to use

• tidy.ts: Doesn't preserve timestamps.
• Arima_tidiers: Not usable for autoplot.
• glm_tidiers: fortify is already defined in {ggplot2}. Considering to use autoplot internally for simplification.
• lm_tidiers: Same as glm.
• htest_tidiers: Plotting single test result is not very useful. Reconsider if there is good example.
• tidy.pairwise.htest: Doesn't contain confidence intervals. Considering to use {pairwiseCI}
• tidy.ftable: No need to use, simply call as.data.frame.

[sinhrks]

May need to revisit this, as ggplot2::fortify may be deprecated in future. broom::augment will be a successor?
