histNormal(
  x,
  xlab = deparse(substitute(x)),
  ylab = "Frequency",
  main = deparse(substitute(x)),
  breaks = "Sturges",
  ylim = NULL
)

Arguments

x	A numeric vector
xlab	`x-axis` label
ylab	`y-axis` label
main	Plot title
breaks	Passed to `hist()` function (`?hist` for details)
ylim	`y-axis` limits

Examples

# histNormal() with data from a SMART survey in Kabul, Afghanistan
# (dist.ex01)
svy <- dist.ex01
histNormal(svy$muac)
histNormal(svy$haz)
histNormal(svy$waz)
histNormal(svy$whz)
