Plots a polarity Object

Usage

"plot"(x, bar.size = 5, low = "blue", mid = "grey99", high = "red", ave.polarity.shape = "+", alpha = 1/4, shape = 19, point.size = 2.5, jitter = 0.1, nrow = NULL, na.rm = TRUE, order.by.polarity = TRUE, plot = TRUE, error.bars = TRUE, error.bar.height = 0.5, error.bar.size = 0.5, error.bar.color = "black", ...)

Arguments

x
The polarity object.
bar.size
The size of the bars used in the Gantt plot.
low
The color to be used for lower values.
mid
The color to be used for mid-range values (default is a less striking color).
high
The color to be used for higher values.
ave.polarity.shape
The shape of the average polarity score used in the dot plot.
alpha
Transparency level of points (ranges between 0 and 1).
shape
The shape of the points used in the dot plot.
point.size
The size of the points used in the dot plot.
jitter
Amount of vertical jitter to add to the points.
nrow
The number of rows in the dotplot legend (used when the number of grouping variables makes the legend too wide). If NULL no legend if plotted.
na.rm
logical. Should missing values be removed?
order.by.polarity
logical. If TRUE the group polarity plot will be ordered by average polarity score, otherwise alphabetical order is assumed.
plot
logical. If TRUE the plot will automatically plot. The user may wish to set to FALSE for use in knitr, sweave, etc. to add additional plot layers.
error.bars
logical. If TRUE error bars are added to the polarity dot plot using the standard error of the mean polarity score.
error.bar.height
The height of the error bar ends.
error.bar.size
The size/thickness of the error bars.
error.bar.color
The color of the error bars. If NULL each bar will be colored by grouping variable.
...
ignored

Plots a polarity Object

Value

Invisibly returns the ggplot2 objects that form the larger plot.

Description

Plots a polarity object as a heat map Gantt plot with polarity over time (measured in words) and polarity scores per sentence. In the dotplot plot the black dots are the average polarity per grouping variable.
