This function plots a heat map to visualize the coverage of the time-scope-units of the data. Options include total number of cases per time-scope-unit or relative number in percentage.

overview_heat(
  dat,
  id,
  time,
  perc = FALSE,
  exp_total,
  xaxis = "Time frame",
  yaxis = "Sample",
  col_low = "#dceaf2",
  col_high = "#2A5773",
  label = TRUE
)

Arguments

dat

The data set

id

The scope (e.g., country codes or individual IDs). The axis is ordered in ascending order by default.

time

The time (e.g., time periods given by years, months, ...)

perc

If FALSE (default) plot returns the total number of observations per time-scope-unit. If TRUE, it returns the number of observations per time-scope-unit in percentage

exp_total

Expected total number of observations (i.e. maximum) for time unit.

xaxis

Label of your x axis ("Time frame" is default)

yaxis

Label of your y axis ("Sample" is default)

col_low

Hex color code for the lowest value (default is "#dceaf2")

col_high

Hex color code for the lowest value (default is "#2A5773")

label

If TRUE (default), the total number of observations/percentages of observations are displayed. If FALSE, it returns no labels.

Value

A ggplot figure that presents sample coverage visually

Examples

data(toydata) overview_heat(toydata, ccode, year, perc = TRUE, exp_total = 12)
