Descriptive statistics

Description

GUI for descriptive statistics.

Usage

stat.desc(X = NULL, groupes = NULL, data = NULL, tr = 0.1, type = 3, plot = T, ref = T, save = F, html = T)

Arguments

X	character or vector. Variable names for which descriptive must be done
groupes	character or vector. Grouping variable. Must be a factor variable
data	name of dataframe in which to find variables
tr	trim value. The value must be between 0 and 0.5
type	Which estimate for skew and kurtosis. Value between 1 and 3. See ?describe
plot	Logical. Should the plot be printed ?
ref	Logical. Should references be printed ?
save	Logical. Should results be saved ?
html	Logical. Should results be knit in html?

Details

Results from describeBy from psych package or summary function, depending on variable type. Violin plots are created by ggplot2. The red point is the mean and point range one SD. Each value is also plotted If saved is true, an rtf document and compatible R file are created in the working directory. The value 'FALSE' for ref is used in internal easieR function, in order to avoid packages used for this function to be printed. Note : If the groupes argument is not a factor variable, a message box asks whether you want to convert the variable in a factor.
