Description

Draw a line plot using ggplot2

Usage

ggplot2.lineplot(data, xName, yName, groupName = NULL, addPoint = FALSE,
  pointSize = 1.5, pointShape = 19, pointFill = NULL,
  pointColor = "black", arrow = NULL, xAxisType = c("categorical",
  "continuous"), groupColors = NULL, brewerPalette = NULL, ...)

Arguments

data	data.frame or a numeric vector. Columns are variables and rows are observations.
xName	The name of column containing x variable (i.e groups).
yName	The name of column containing y variable.
groupName	The name of column containing group variable. This variable is used to color plot according to the group.
addPoint	If TRUE, points are added to the plot. Default value is FALSE.
pointSize, pointShape, pointFill, pointColor	Modify point size, shape, fill and color.
arrow	arrow is function from package grid. This function Describe arrows to add to a line. See ?grid::arrow for more details. Usage : arrow=arrow(). Default value is NULL.
xAxisType	Indicate the type of x-axis. Possible values =c("categorical", "continuous"). Default value is "categorical". When the variable on the x-axis is numeric, it is sometimes useful to treat it as continuous, and sometimes useful to treat it as categorical.
groupColors	Color of groups. groupColors should have the same length as groups.

                 total_bill = c(14.89, 17.23))

#plot
ggplot2.lineplot(data=df, xName="time", yName='total_bill',
                mainTitle="Plot of total bill\n per time of day",
                xtitle="Time of day", ytitle="Total bill")

#Or use this
plot<-ggplot2.lineplot(data=df, xName="time", yName='total_bill')
plot<-ggplot2.customize(plot,  mainTitle="Plot of total bill\n per time of day",
                      xtitle="Time of day", ytitle="Total bill")
