Venn Diagram by Grouping Variable

Usage

trans_venn(text.var, grouping.var, stopwords = NULL, rm.duplicates = TRUE, title = TRUE, title.font = NULL, title.color = "black", title.cex = NULL, title.name = NULL, legend = TRUE, legend.cex = 0.8, legend.location = "bottomleft", legend.text.col = "black", legend.horiz = FALSE, ...)

Arguments

text.var
The text variable.
grouping.var
The grouping variables. Default NULL generates one word list for all text. Also takes a single grouping variable or a list of 1 or more grouping variables.
stopwords
Words to exclude from the analysis.
rm.duplicates
logical. If TRUE removes the duplicated words from the analysis (only single usage is considered).
title
logical. IF TRUE adds a title corresponding to the grouping.var.
title.font
The font family of the cloud title.
title.color
A character vector of length one corresponding to the color of the title.
title.cex
Character expansion factor for the title. NULL and NA are equivalent to 1.0
title.name
A title for the plot.
legend
logical. If TRUE uses the names from the target.words list corresponding to cloud.colors.
legend.cex
Character expansion factor for the legend. NULL and NA are equivalent to 1.0.
legend.location
The x and y co-ordinates to be used to position the legend. The location may also be specified by setting x to a single keyword from the list "bottomright", "bottom", "bottomleft", "left", "topleft", "top", "topright", "right" and "center". This places the legend on the inside of the plot frame at the given location.
legend.text.col
The color used for the legend text.
legend.horiz
logical; if TRUE, set the legend horizontally rather than vertically.
...
Other arguments passed to plot.

Venn Diagram by Grouping Variable

Value

Returns a Venn plot by grouping variable(s).

Description

Produce a Venn diagram by grouping variable.

Warning

The algorithm used to overlap the Venn circles becomes increasingly overburdened and less accurate with increased grouping variables. An alternative is to use a network plot with {codeDissimilarity measures labeling the edges between nodes (grouping variables) or a heat map (qheat).

Examples

## <strong>Not run</strong>: 
# with(DATA , trans_venn(state, person, legend.location = "topright"))
# #the plot below will take a considerable amount of time to plot
# with(raj.act.1 , trans_venn(dialogue, person, legend.location = "topleft"))
# ## <strong>End(Not run)</strong>
