)A ggplot class object.
The target data frame for the bar chart.
A required string that sets the x axis discrete variable name from 'df'.
Sets the y axis numeric variable name from 'df'. If this variable is NULL
the bar heights will be proportional to the number of cases in the levels of 'aes_x'.
If 'aes_y' is not NULL, the bar heights represent this parameter's values across the 'aes_x' levels.
Sets the variable name from 'df' for the aesthetic mapping for color.
Sets the variable name from 'df' for the aesthetic mapping for fill.
A string that sets the bar positions. Acceptable values are "dodge"(side by side), "identity"(overlap) or "stack".
A string that sets the overall title.
A string that sets the overall subtitle.
A string that sets the caption.
A logical which if TRUE centers both the 'title' and 'subtitle'.
A string that sets the x axis title. If NULL (the default) then the x axis title does not appear.
A string that sets the y axis title. If NULL (the default) then the y axis title does not appear.
A logical that controls the appearance of the x axis tics.
A logical that controls the appearance of the y axis tics.
A numeric that sets the angle of rotation for the x tic label. When x tic labels are long, a value of 40 for this argument usually works well.
A logical which if TRUE rotates the y tic labels 90 degrees for enhanced readability.
A string that sets the fill color attribute for the bars.
A string that sets the outline color attribute for the bars.
A numeric that sets the alpha component attribute to 'bar_color'.
A numeric that sets the bar's outline line width attribute.
A numeric that sets the width attribute of the bars.
If 'aes_x' is numeric then this parameter is a numeric vector that defines the major breaks/intervals for the x axis. Interval labels are created and their respective counts are displayed.
A numeric 2 element vector that sets the minimum and maximum for the y axis.
Use NA to refer to the existing minimum and maximum.
A numeric vector or function that defines the exact major tic locations along the y axis.
A numeric vector or function that defines the exact minor tic locations along the y axis.
A character vector with the same length as 'y_major_breaks', that labels the major tics.
A numeric that sets the font size along the axis'. Default is 11.
A logical which if TRUE will flip the x and y axis'.
A string which will order the bars in a specific direction. Acceptable values are "asc" or "desc"
A logical which if TRUE will label each bar with its value.
A numeric that sets the size of the label.
A string that sets the label's color.
A string that sets the label's font face. Acceptable values are "plain", "bold", "italic", "bold.italic".
A numeric that sets the label's alpha value.
A logical that controls the appearance of major grids.
A logical that controls the appearance of minor grids.
A string in hexidecimal or color name that sets the plot panel's color. The default is "white".
A string in hexidecimal or color name that sets the plot panel's border color. The default is "black".
A logical that controls the appearance of the legend.
A string that sets the legend position. Acceptable values are "top", "bottom", "left", "right".
A numeric that sets the legend width in cm.
A numeric that sets the legend height in cm.
A string that sets the legend's background color.
A logical that controls the appearance of a console warning when Na's are removed.
A character string with the directory and file name to produce a png image of the plot.
A numeric vector that sets the width and height of the png image in pixels. The default is c(480,480). There are 37.8 pixels in a centimeter.
