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

     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)))

_A_r_g_u_m_e_n_t_s:

       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

     examples

     'qplot' provides a quick way to create simple plots.
