Barplot of missing values proportion in each metabolite

plot_NA_percent() creates a barplot showing the proportion of missing values in each metabolite. Optionally, for every metabolite, it can include the division by the type of missing values or display the proportion of missing values in each group level.

Usage

plot_NA_percent(dat, type = "joint", interactive = TRUE)

Arguments

dat

a raw_data object. Output of read_data() function.

type

a character string indicating which type of plot to return. This can be either "joint", "NA_type" or "group". Default type is "joint", which creates a plot of missing values percents in each metabolite. "NA_type" additionally splits missing values by type, and "group" includes the ratios in every group level.

interactive

logical. If TRUE (default), a ggiraph interactive plot is returned; otherwise, a standard ggplot object is produced.

Examples

path <- get_example_data("small_biocrates_example.xls")
dat <- read_data(path)
print(plot_NA_percent(dat))
print(plot_NA_percent(dat, "NA_type"))
dat <- add_group(dat, "group")
print(plot_NA_percent(dat, "group"))
