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

_U_s_a_g_e:

     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, ...)

_A_r_g_u_m_e_n_t_s:

       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
