qplot {ggplot} | R Documentation

## Quick plot.

### Description

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

### Usage

    qplot(x, y = NULL, data, facets = . ~ ., margins=FALSE, types = "point", colour = NULL, size = NULL, shape = NULL, linetype = NULL, fill = NULL, id=NULL, weight=NULL, xlim = c(NA, NA), ylim = c(NA, NA), log = "", main = NULL, xlab = deparse(substitute(x)), ylab = deparse(substitute(y)), add=NULL, ...)

### Arguments

`x` | x values
`y` | y values
`data` | data frame to use (optional)
`facets` | facetting formula to use
`margins` | grob type(s) to draw (can be a vector of multiple names)
`types` | vector to use for colours
`colour` | vector to use for sizes
`size` | vector to use for shapes
`shape` | vector to use for line type
`linetype` | vector to use for fill colour
`fill` | vector to use for ids
`id` | vector to use for weights
`weight` | limits for x axis (defaults to range of data)
`xlim` | limits for y axis (defaults to range of data)
`ylim` | which variables to log transform ("x", "y", or "xy")
`log` | character vector or expression for plot title
`main` | character vector or expression for x axis label
`xlab` | character vector or expression for y axis label
`ylab` | if specified, build on top of this ggplot, rather than creating a new one
`add` | other arguments passed on to the grob functions
`...` |

### Examples

    qplot(LETTERS[1:5], 1:5, type="rect", main="Blah", xlab="Hi")
    qplot(LETTERS[1:5], 1:5, type=c("tile", "point"), main="Blah", xlab="Hi", ylim=c(0,10), col=1:5)
    qplot(wt, mpg, data=mtcars, col=cyl, shape=cyl, size=wt)
