plot.polarity_count function

Plots a polarity_count Object

Plots a polarity_count 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.

## S3 method for class 'polarity_count'
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_count 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

Returns

Invisibly returns the ggplot2 objects that form the larger plot.
