bar_line_ggplot: Plot bar and line figure in the same figure

Description Usage Arguments Value Examples

This function use the given x_var and bar_var to draw bar plot but use the given x_var and the first column in dataset except x_var and bar_var to draw line plot. The principle of drawing bar and line plot in one figure is to map the graduation of line plot to the main Y axis and write the actual graduation of line plot to the secondary Y axis.

You can control the top and bottom blank of line plot using parameters scale_blank_div and specify the range of line plot in the main Y axis using parameters scale_interval. These two parameters can easily control the scope of line plot to make it not conflict with bar plot.

This function has the auto-detect function to change variable name in English to axis name in Chinese. The information in option you have set before run r plot code is used as a convertor.

`dataset`	data frame containing at least 3 columns.
`x_var`	character. The column name that will be the X axis in the plot.
`bar_var`	character, default `"sample_size"`. The column name that will be used to draw bar plot.
`scale_blank_div`	numeric, default 5. It directly affect the proportion of the figure height that line plot occupied. The line plot in the figure will occupies \frac{scale_blank_div-2}{scale_blank_div} of the figure height and leave blanks in the top and bottom \frac{1}{scale_blank_div}.
`scale_interval`	numeric vector of length 2. The interval of line plot in the main Y axis.
`main_axis_name`	character. The name of main Y axis. If missing, the function will use information in `option` to auto-detect the name according to `bar_var`.
`sec_axis_name`	character. The name of secondary Y axis. If missing, the function will use information in `option` to auto-detect the name according to `line_var`.
`x_axis_name`	character. The name of X axis. If missing, the function will use information in `option` to auto-detect the name according to `x_var`.
`bar_fill_palette`	character of character vector. It is the color palette of bar plot.
`line_color`	character of color. It is the color of line in line plot.
`point_color`	character of color. It is the color of point in line plot.
`legend_pos`	character of character vector. It controls the position of legend.
`label_size`	numeric, default 4. It controls the size of lebel of line plot. DO NOT make it less than 4 of larger than 6 or it will look ugly.
