plotmuac: Plots MUAC z-scores and percentiles on references curves.

In MUACz: Generate MUAC and BMI z-Scores and Percentiles for Children and Adolescents

Description

Plots individual MUAC z-scores and percentiles on standardized growth references using the LMS method for children and adolescents aged 3 months to 19 years.

Usage

plotmuac(
  age,
  sex,
  muac,
  age_range = "3-60",
  graphtype = "z-scores",
  lwd = 1,
  line.color = "skyblue",
  line.type = "solid",
  shape = 2,
  size.label = 2,
  size.score = 4,
  Notes = FALSE
)

Arguments

age	a numeric value (in months) between 3 and 228 depending on the age_range.
sex	preferably numeric (1 = Male, 2 = Female). Strings (such as "Male", "Female") can also be used.
muac	a numeric mid upper arm circumference value in cm.
age_range	age range in months. Input has to be characters. Options allowed are: "3-60" which is the default, or "60-228".
graphtype	A character input is required: "z-scores" or "percentiles".
lwd	Line width allows you to specify a numeric value that control the width of the line plots. By dafult, it is set to 1.
line.color	The color of the lines. It is set to "skyblue" by default.
line.type	Type of line such as: "solid", "dotted", "dashed", "blank", "dotdash", "twodash", "longdash"
shape	of the individual point (marker)
size.label	size of the label for calculated z-score or percentile
size.score	refers to the size of the text for the calculated z-scores (-3,-2,-1,0,1,2,3) or the percentiles.
Notes	Is FALSE by default. If set to TRUE, 'notes' will be printed on the console about the nature, range of variables allowed and number of records processed.

Value

Plots z-scores or percentiles with a mark indicating where the individual person lies within the standardized reference curves.
