In pguIMP: 'pguIMP'

Description

Handles the pguIMP dataset.

Format

R6::R6Class object.

Details

Stores the pguIMP dataset as instance variable and keeps track of the attributes of interest. Provides additionally fast access to several statistical information about the data set. This object is used by the shiny based gui and is not for use in individual R-scripts!

Method new()

Clears the heap and indicates that instance of pguIMP::pgu.data is removed from heap.

Summarizes information on the instance variable rawData and retruns it in form of a compact data frame.

Summarizes a vector of numericals and returns summary.

Iterativley calls the function summarize_numerical_data on all numerical attributes of the instance variable rawData and returns the result in form of a data frame.

Calls the function calculate_statistics filters the result for the attribute names and arithmetic mean values. and returns the result in form of a data frame.

Calls the class' function dataStatistics filters the result for the attribute names and information about missing values. and returns the result in form of a data frame.

Creates and returns a new pguIMP::pgu.data object.

Usage

pgu.data$new(data_df = "tbl_df")

Arguments

data_df
