qplot {ggplot2} | R Documentation

## Quick plot.

### Description

Quick plot is a convenient wrapper function for creating simple ggplot plot objects.

### Usage

    qplot(x, y = NULL, z=NULL, ..., data, facets = . ~ ., margins=FALSE, geom = "point", stat=list(NULL), position=list(NULL), xlim = c(NA, NA), ylim = c(NA, NA), log = "", main = NULL, xlab = deparse(substitute(x)), ylab = deparse(substitute(y)))

### Arguments

`x` | x values
`y` | y values
`z` | z values
`...` | other arguments passed on to the geom functions
`data` | data frame to use (optional)
`facets` | facetting formula to use
`margins` | whether or not margins will be displayed
`geom` | geom to use (can be a vector of multiple names)
`stat` | statistic to use (can be a vector of multiple names)
`position` | position adjustment to use (can be a vector of multiple names)
`xlim` | limits for x axis (aesthetics to range of data)
`ylim` | limits for y axis (aesthetics to range of data)
`log` | which variables to log transform ("x", "y", or "xy")
`main` | character vector or expression for plot title
`xlab` | character vector or expression for x axis label
`ylab` | character vector or expression for y axis label

### Details

### Examples

    # Use data from data.frame
    qplot(mpg, wt, data=mtcars)
    qplot(mpg, wt, data=mtcars, colour=cyl)
    qplot(mpg, wt, data=mtcars, size=cyl)
    qplot(mpg, wt, data=mtcars, facets=vs ~ am)

    # Use data from workspace environment
    attach(mtcars)
    qplot(mpg, wt)
    qplot(mpg, wt, colour=cyl)
    qplot(mpg, wt, size=cyl)
    qplot(mpg, wt, facets=vs ~ am)

    # Use different geoms
    qplot(mpg, wt, geom="path")
    qplot(factor(cyl), wt, geom=c("boxplot", "jitter"))
