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,...)
mytable2(formula, data, max.ylev = 5, digits = 2, method = 1,
show.all = FALSE)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.
A data.frame contains data for analysis
An integer indicating the maximum number of levels of grouping variable ('y'). If a colummn have unique values less than max.ylev it is treated as a categorical variable. Default value is 5.
An integer indicating the number of decimal places (round) or significant digits (signif) to be used. Default value is 1.
An integer indicating methods for continuous variables. Possible values in methods are
forces analysis as normal-distributed
forces analysis as continuous non-normal
performs a Shapiro-Wilks test to decide between normal or non-normal
Default value is 1.
A logical value indicating whether or not all statistical values have to be shown in table. Default value is FALSE.
An object of class "cbind.mytable"
