rxResultsDF: Crosstab Counts or Sums Data Frame

  • Article

Description

Obtain a counts, sums, or means data frame from an analysis object.

Usage

 ## S3 method for class `rxCrossTabs':
rxResultsDF  (object, output = "counts", element = 1,
     integerLevels = NULL, integerCounts = TRUE, ...)
 ## S3 method for class `rxCube':
rxResultsDF  (object, output = "counts",
     integerLevels = NULL, integerCounts = TRUE, ...)
 ## S3 method for class `rxLinMod':
rxResultsDF  (object, output = "counts", 
     integerLevels = NULL, integerCounts = TRUE, ...)
 ## S3 method for class `rxLogit':
rxResultsDF  (object, output = "counts", 
     integerLevels = NULL, integerCounts = TRUE, ...)
 ## S3 method for class `rxSummary':
rxResultsDF  (object, output = "stats", element = 1,
     integerLevels = NULL, integerCounts = TRUE, useRowNames = TRUE, ...)

Arguments

object

object of class rxCrossTabs, rxCube, rxLinMod, rxLogit, or rxSummary.

output

character string specifying the type of output to display. Typically this is "counts", or for rxSummary "stats". If there is a dependent variable in the rxCrossTabs formula, "sums" and "means"can be used.

element

integer specifying the element number from the object list to extract. Currently only 1 is supported.

integerLevels

logical scalar or NULL. If TRUE, the first column of the returned data frame will be converted to integers. If FALSE, it will be a factor column. If NULL, it will be returned as an integer column if it was wrapped in an F() in the formula.

integerCounts

logical scalar. If TRUE, the counts or sums in the returned data frame will be converted to integers. If FALSE, they will be numeric doubles.

useRowNames

logical scalar. If TRUE, the names of the variables for which there are results will be put into the row names for the data frame rather than in a separate Names variable.

...

additional arguments to be passed directly to the underlying print method for the output list object.

Details

Method to access counts, sums, and means data frames from RevoScaleR analysis objects.

Value

a data frame containing the computed counts, sums, or means.

Examples


 admissions <- as.data.frame(UCBAdmissions)
 myCrossTab1 <- rxCrossTabs(~Gender : Admit, data = admissions)
 countsDF1 <- rxResultsDF(myCrossTab1)

 # If a dependent variable is used, "sums" and "means" can be used
 myCrossTab2 <- rxCrossTabs(Freq ~ Gender : Admit, data = admissions)
 countsDF <- rxResultsDF(myCrossTab2)
 sumsDF <- rxResultsDF(myCrossTab2, output = "sums")
 meansDF <- rxResultsDF(myCrossTab2, output = "means")
