mytable2: Produce combined table for descriptive statistics

Description

Produce table for descriptive statistics by two grouping variables for several variables easily. Depending on the nature of these variables, different descriptive statistical methods were used(t-test, ANOVA,Kruskal-Wallis, chisq, Fisher,...)

Usage

mytable2(
  formula,
  data,
  use.labels = TRUE,
  use.column.label = TRUE,
  max.ylev = 5,
  maxCatLevel = 20,
  digits = 2,
  method = 1,
  catMethod = 2,
  show.all = FALSE,
  exact = FALSE,
  show.total = FALSE,
  origData = NULL
)

Arguments

formula

An object of class "formula". Left side of ~ must contain two grouping variables in an additive way(e.g. sex+group~), and the right side of ~ must have variables in an additive way.

data

A data.frame contains data for analysis

use.labels

Logical. Whether or not use labels.

use.column.label

Logical. Whether or not use column labels.

max.ylev

An integer indicating the maximum number of levels of grouping variable ('y'). If a column have unique values less than max.ylev it is treated as a categorical variable. Default value is 5.

maxCatLevel

An integer indicating the maximum number of unique levels of categorical variable. If a column have unique values more than maxCatLevel, categorical summarization will not be performed.

digits

An integer indicating the number of decimal places (round) or significant digits to be used. Default value is 1.

method

An integer indicating methods for continuous variables. Possible values in methods are

1: forces analysis as normal-distributed
2: forces analysis as continuous non-normal
3: performs a Shapiro-Wilk test to decide between normal or non-normal

Default value is 1.

catMethod

An integer indicating methods for categorical variables. Possible values in methods are

0: Perform chisq.test first. If warning present, perform fisher test
1: Perform chisq.test without continuity correction
2: Perform chisq.test with continuity correction
3: perform fisher.test
4: perform prop.trend test

Default value is 2.

show.all

A logical value indicating whether or not all statistical values have to be shown in table. Default value is FALSE.

exact

A logical value indicating whether or not permit call with approximate parameter. If true, only exact column name permitted.Default value is FALSE.

show.total

A logical value indicating whether or not show total group value. Default value is FALSE.

origData

A data.frame contains data for analysis

Value

An object of class "cbind.mytable"
