set_size.scale_max = NULL)
```

##### Arguments

- data
Data set

- nsets
Number of sets to look at

- nintersects
Number of intersections to plot. If set to NA, all intersections will be plotted.

- sets
Specific sets to look at (Include as combinations. Ex: c("Name1", "Name2"))

- keep.order
Keep sets in the order entered using the sets parameter. The default is FALSE, which orders the sets by their sizes.

- set.metadata
Metadata that offers insight to an attribute of the sets. Input should be a data frame where the first column is set names, and the remaining columns are attributes of those sets. To learn how to use this parameter it is highly suggested to view the set metadata vignette. The link can be found on the package's GitHub page.

- intersections
Specific intersections to include in plot entered as a list of lists. Ex: list(list("Set name1", "Set name2"), list("Set name1", "Set name3")). If data is entered into this parameter the only data shown on the UpSet plot will be the specific intersections listed.

- matrix.color
Color of the intersection points

- main.bar.color
Color of the main bar plot

- mainbar.y.label
The y-axis label of the intersection size bar plot

- mainbar.y.max
The maximum y value of the intersection size bar plot scale. May be useful when aligning multiple UpSet plots horizontally.

- sets.bar.color
Color of set size bar plot

- sets.x.label
The x-axis label of the set size bar plot

- point.size
Size of points in matrix plot

- line.size
Width of lines in matrix plot

- mb.ratio
Ratio between matrix plot and main bar plot (Keep in terms of hundredths)

- expression
Expression to subset attributes of intersection or element query data. Enter as string (Ex: "ColName > 3")

- att.pos
Position of attribute plot. If NULL or "bottom" the plot will be at below UpSet plot. If "top" it will be above UpSet plot

- att.color
Color of attribute histogram bins or scatterplot points for unqueried data represented by main bars. Default set to color of main bars.

- order.by
How the intersections in the matrix should be ordered by. Options include frequency (entered as "freq"), degree, or both in any order.

- decreasing
How the variables in order.by should be ordered. "freq" is decreasing (greatest to least) and "degree" is increasing (least to greatest)

- show.numbers
Show numbers of intersection sizes above bars

- number.angles
The angle of the numbers atop the intersection size bars

- group.by
How the data should be grouped ("degree" or "sets")

- cutoff
The number of intersections from each set (to cut off at) when aggregating by sets

- queries
Unified query of intersections, elements, and custom row functions. Entered as a list that contains a list of queries. query is the type of query being conducted. params are the parameters of the query (if any). color is the color of the points on the plot that will represent the query. If no color is selected one will be provided automatically. active takes TRUE or FALSE, and if TRUE, it will overlay the bars present with the results from the query. If FALSE a tick mark will indicate the intersection size. See examples section on how to do this.

- query.legend
Position query legend on top or bottom of UpSet plot

- shade.color
Color of row shading in matrix

- shade.alpha
Transparency of shading in matrix

- matrix.dot.alpha
Transparency of the empty intersections points in the matrix

- empty.intersections
Additionally display empty sets up to nintersects

- color.pal
Color palette for attribute plots

- boxplot.summary
Boxplots representing the distribution of a selected attribute for each intersection. Select attributes by entering a character vector of attribute names (e.g. c("Name1", "Name2")). The maximum number of attributes that can be entered is 2.

- attribute.plots
Create custom ggplot using intersection data represented in the main bar plot. Prior to adding custom plots, the UpSet plot is set up in a 100 by 100 grid. The attribute.plots parameter takes a list that contains the number of rows that should be allocated for the custom plot, and a list of plots with specified positions. nrows is the number of rows the custom plots should take up. There is already 100 allocated for the custom plot. plots takes a list that contains a function that returns a custom ggplot and the x and y aesthetics for the function. ncols is the number of columns that your ggplots should take up. See examples for how to add custom ggplots.

- scale.intersections
The scale to be used for the intersection sizes. Options: "identity", "log10", "log2"

- scale.sets
The scale to be used for the set sizes. Options: "identity", "log10", "log2"

- text.scale
Numeric, value to scale the text sizes, applies to all axis labels, tick labels, and numbers above bar plot. Can be a universal scale, or a vector containing individual scales in the following format: c(intersection size title, intersection size tick labels, set size title, set size tick labels, set names, numbers above bars)

- set_size.angles
Numeric, angle to rotate the set size plot x-axis text

- set_size.show
Logical, display the set sizes on the set size bar chart

- set_size.numbers_size
If set_size.show is TRUE, adjust the size of the numbers

- set_size.scale_max
Increase the maximum of set size scale

##### Details

Visualization of set data in the layout described by Lex and Gehlenborg in http://www.nature.com/nmeth/journal/v11/n8/abs/nmeth.3033.html. UpSet also allows for visualization of queries on intersections and elements, along with custom queries queries implemented using Hadley Wickham's apply function. To further analyze the data contained in the intersections, the user may select additional attribute plots to be displayed alongside the UpSet plot. The user also has the the ability to pass their own plots into the function to further analyze data belonging to queries of interest. Most aspects of the UpSet plot are customizable, allowing the user to select the plot that best suits their style. Depending on how the features are selected, UpSet can display between 25-65 sets and between 40-100 intersections.

##### Note

Data set must be formatted as described on the original UpSet github page: http://github.com/VCG/upset/wiki.
