auto_bar_categ.Rd

Automatically generates barplot stratified by group variables with or without percentages.

Usage

auto_bar_categ(
  data,
  groupvar = NULL,
  bar_args = NULL,
  theme_func = theme_serene,
  lang_labs = NULL,
  showpercent = TRUE,
  drop_na = TRUE
)

Arguments

data

Name of the dataframe

groupvar

Name of the grouping variable. Grouping variable will be used in "fill" for aesthetics argument in the creation of each ggplot object. If not provided, the function take each variable as grouping and does not display the "fill" legend.

bar_args

showpercent

Logical atribute to indicate if the graph should include percentages

drop_na

Remove NAs from provided dataframe

Value

Returns a list containing all barplots as ggplot object. Can be accessed via $ operator

Examples

data<-data.frame(categ = rep(letters[1:2], 10),
var1 = rep(LETTERS[4:5], 10),
var2 = rep(LETTERS[6:7], 10),
var3 = rep(LETTERS[8:9], 10),
var4 = rep(LETTERS[10:11], 10))

data$categ <- as.factor(data$categ)
data$var1 <- as.factor(data$var1)
data$var2 <- as.factor(data$var2)
data$var3 <- as.factor(data$var3)
data$var4 <- as.factor(data$var4)

barplot_list<-auto_bar_categ(data = data, groupvar = "categ", lang_labs = "EN")

barplot_list$var1



# Example using `groupvar` argument as `NULL`
