`df2col`	Input data, a 2 column dataframe
`...`	Pass any other parameter of the corresponding plotting function(most of them should work).
`color`	Filling color of the symbols
`xlim`	Manually set the range of canvas in X dimension
`ylim`	Defines the Y axis range. Replacement for the standard "ylim" argument.
`zlim`	Manually set the range of colors numbers (Z dimension)
`nlevels`	Number of steps in the color gradient
`pch`	Define the symbol for each data point. A number 0-25 or any string between ""-s.
`cex`	Size of the symbols
`plotname`	The name of the file saved.
`plot.title`	The title of the plot.
`plot.axes`	Draw axis ticks
`key.title`	...
`key.axes`	...
`asp`	numeric, giving the aspect ratio y/x. See help('plot.window').
`xaxs`	The style of axis interval calculation to be used for the X-axis. See help('par').
`yaxs`	The style of axis interval calculation to be used for the X-axis. See help('par').
`las`	numeric in 0, 1, 2, 3; the style of axis labels. See help('par').
`axes`	Draw axes and box
`frame.plot`	No description.
`xlab`	X axis label
`ylab`	Y axis label
`savefile`	Save plot as pdf in OutDir, TRUE by default.
`w`	Width of the saved pdf image, in inches.
`h`	Height of the saved pdf image, in inches.
`incrBottMarginBy`	Increase the blank space at the bottom of the plot. Use if labels do not fit on the plot.
`mdlink`	Insert a .pdf and a .png image link in the markdown report, set by "path_of_report".
`PNG`	Set to true if you want to save the plot as PNG instead of the default PDF.
