AgrMcDt: Agregate Micro Data

Description

AgrMcDt creates IData objects by agregating a Data Frame of Micro Data.

Usage

AgrMcDt(MicDtDF, agrby, agrcrt="minmax")

Value

An object of class IData with the data set of Interval-valued variables resulting from the aggregation performed.

Arguments

MicDtDF

A data frame with the original values of the micro data.

agrby

A factor with categories on which the micro data should be aggregated.

agrcrt

The aggregation criterion. Either the ‘minmax’ string, or a two dimensional vector with the prob. value for the left (lower) percentile, followed by the prob. value for the right (upper) percentile, used in the aggregation.

Examples

# Create an Interval-Data object by agregating the microdata consisting 
# of 336776 NYC flights included in the FlightsDF data frame, 
# by the statistical units specified in the FlightsUnits factor.

Flightsminmax <- AgrMcDt(FlightsDF,FlightsUnits)

#Display the first and last observations

head(Flightsminmax)
tail(Flightsminmax)

#Print summary statistics

summary(Flightsminmax)

if (FALSE) {

# Repeat this procedure using now the 10th and 90th percentiles.

Flights1090prcnt <- AgrMcDt(FlightsDF,FlightsUnits,agrcrt=c(0.1,0.9))

#Display the first and last observations

head(Flights1090prcnt)
tail(Flights1090prcnt)

summary(Flights1090prcnt)
