In gmonette/yscs: Collection of tools used in York University's Statistical Consulting Service

Description

The yscs package is a collection of functions and datasets intended primarily for statistical consulting, with a particular emphasis on longitudinal and hierarchical data analysis.

Wald tests and linear hypothesis matrices

• wald quick Wald tests – optionally building hypothesis matrices from regular expressions

• walddf version of wald that returns a data frame

• as.data.frame.wald return a data frame from a wald object

• coef.wald method to extract estimated coefficients

• print.wald printing method

• Lfx creates hypothesis matrices for derivatives and differences. Add example for factor differences

• M constructor for M objects to generate portions of design and hypothesis matrices. Used with Lfx

• Lall for lmer objects

• Lc for lmer objects

• Lcall superseded by Lfx

• Ldiff superseded by Lfx

• Lequal superseded by Lfx

• Lform superseded by Lfx

• Lmat superseded by Lfx

• Lmu for lmer objects

• Lrm superseded by Lfx?

• rpfmt format estimated values and p-values from a wald test

Utilities for fitted objects

• getData get data frame from a fitted object

• getFix get fixed effects from a fitted object

• getX get X matrix from fitted object

• gpanel.fit plot fitted values and confidence band

• Vcov get estimated variance covariance of fixed effects from a fitted object

Multilevel data frames

• long is an attempt to simplify the functions 'long' and 'tolong' in spida which, in turn, are attempts at simplifying calls to

• stats::reshape

Datasets

• hsfull

• iq

Miscellaneous utility functions

• sortdf sort rows of a data frame – useful in a magrittr pipeline

• assn assign – useful in a magrittr pipeline

• disp utility to display value of a variable – useful for debugging

• getFactorNames get names of variables that are factors in a data frame

• %less% synonym for setdiff

• labs assign, extract and print labels for various objects

• pch generate plotting character mnemonically

• pfmt format p-values

• print.cat

• rnd round a vector to keep significant digits in variation in values

• run evaluate a string as a command with try

• grepv grep(..., value = TRUE)
