Appends a column to a data frame containing hex codes (ready for usage in a plot) The values are determined by a user-specified column.

1 2	df_color(df, column, output_name = "color", min_color = "green", max_color = "red", method = "hsv", smooth_factor = 2)

`df`	Data frame containing the original data.
`column`	A string containing the name of the column that will determine color.
`output_name`	Name for the column in which the output will be stored. Defaults to "color"
`min_color`	Color to be assigned to the row with the lowest value. Defaults to green.
`max_color`	Color to be assigned to the row with the highest value. Defaults to red.
`method`	Type of gradient. Allows both "rgb" and "hsv". Defaults to "hsv"
`smooth_factor`	Parameter "smooth_factor" for "rgb_weighted_mean" call

A data frame identical to df, except for an extra column (whose name is given by output_name) containing hexcodes
