indivplot function

plot aggregated COD distribution

Produce a bar plot of the aggregated COD distribution as approximate CSMFs for a fitted "insilico" object.

indivplot(
  x,
  type = c("errorbar", "bar")[1],
  top = 10,
  causelist = NULL,
  which.plot = NULL,
  xlab = "Causes",
  ylab = "COD distribution",
  title = "COD distributions for the top causes",
  horiz = TRUE,
  angle = 60,
  fill = "lightblue",
  err_width = 0.4,
  err_size = 0.6,
  point_size = 2,
  border = "black",
  bw = FALSE,
  ...
)

Arguments

• x: object from get.indiv function.
• type: An indicator of the type of chart to plot. "errorbar" for line plots of only the error bars on single population; "bar" for bar chart with error bars on single population.
• top: The number of top causes to plot. If multiple sub-populations are to be plotted, it will plot the union of the top causes in all sub-populations.
• causelist: The list of causes to plot. It could be a numeric vector indicating the position of the causes in the InterVA cause list (see causetext), or a vector of character string of the cause names. The argument supports partial matching of the cause names. e.g., "HIV/AIDS related death" could be abbreviated into "HIV"; "Other and unspecified infect dis" could be abbreviated into "Other and unspecified infect".
• which.plot: Specification of which group to plot if there are multiple.
• xlab: Labels for the causes.
• ylab: Labels for the CSMF values.
• title: Title of the plot.
• horiz: Logical indicator indicating if the bars are plotted horizontally.
• angle: Angle of rotation for the texts on x axis when horiz is set to FALSE
• fill: The color to fill the bars when type is set to "bar".
• err_width: Size of the error bars.
• err_size: Thickness of the error bar lines.
• point_size: Size of the points.
• border: The color to color the borders of bars when type is set to "bar".
• bw: Logical indicator for setting the theme of the plots to be black and white.
• ...: Not used.
