barplotgr: Function for building a barplot for one or two factors

Description

The function creates a barplot of numeric vector by one or two factor.

Usage

barplotgr(
  yvar,
  factors,
  data = data,
  percentage = FALSE,
  errbar = !percentage,
  half.errbar = TRUE,
  conf.level = 0.95,
  xlab = NULL,
  ylab = NULL,
  main = NULL,
  names.arg = NULL,
  bar.col = "black",
  whisker = 0.015,
  args.errbar = NULL,
  legend = TRUE,
  legend.text = NULL,
  args.legend = NULL,
  legend.border = FALSE,
  box = TRUE,
  args.yaxis = NULL,
  mar = c(5, 4, 3, 2),
  ...
)

Value

The function returns the above described graph.

Arguments

yvar: The column having the variable to represent the height of the bars.
factors: A vector having the columns with the factors to be used in the resulting plot. Notice that the last listed factor, will be used in X-axis plot.
data: A data frame having the above described columns.
percentage: Logical value, set to FALSE.
errbar: Please set this option to FALSE.
half.errbar: Optional, default set to TRUE.
