condensed: Condensed: an S3 class for condensed summaries.
In hadley/bigvis: Tools for visualisation of big data sets

Description Usage Arguments S3 methods Examples

This object managed the properties of condensed (summarised) data frames.

condensed(groups, grouped, summary)

is.condensed(x)

as.condensed(x)

`groups`	list of `bin`ed objects
`grouped,summary`	output from C++ condense function
`x`	object to test or coerce

Mathematical functions with methods for binsum object will modify the x column of the data frame and rebin the data, calculating updated summary statistics.

Currently methods are provided for the Math group generic, logical comparison and arithmetic operators, and round_any.

if (require("ggplot2")) {

x <- rchallenge(1e4)
xsum <- condense(bin(x, 1 / 10))

# Basic math operations just modify the first column
autoplot(xsum)
autoplot(xsum * 10)
autoplot(xsum - 30)
autoplot(abs(xsum - 30))

# Similarly, logical operations work on the first col
autoplot(xsum[xsum > 10, ])
}
