In AgroR: Experimental Statistics and Graphics for Agricultural Sciences

Graph: Barplot for Dunnett test

Description

The function performs the construction of a column chart of Dunnett's test.

Usage

bar_dunnett(
  output.dunnett,
  ylab = "Response",
  xlab = "",
  fill = c("white", "#F8766D", "#00BFC4"),
  sup = NA,
  add.mean = TRUE,
  round = 2
)

Arguments

output.dunnett	Numerical or complex vector with treatments
ylab	Variable response name (this argument uses the parse function)
xlab	Treatments name (this argument uses the parse function)
fill	Fill column. Use vector with two elements c(control, different treatment, no difference treatment)
sup	Number of units above the standard deviation or average bar on the graph
add.mean	Plot the average value on the graph (default is TRUE)
round	Number of cells

Value

Returns a column chart of Dunnett's test. The colors indicate difference from the control.
