BMIplot

A simple tool to make a BMI plot of height vs. weight in ggplot2 in R

Examples

Set up demo data set

demo_data=read.csv("http://people.ucsc.edu/~cdobkin/NHIS%202007%20data.csv")%>%
   mutate(Weight=weight/2.20462, #convert pounds to kg
          Height=height*2.54,    #convert inches to cm
          Gender=recode(SEX,`1`="Male",`2`="Female"))%>%
   filter(Height<200,Weight<200) #remove ridiculous entries

Specify lots

makeBMIplot(sample_n(demo_data,100),
            weight="Weight",
            height="Height",
            colFactor="Gender",
            aspect_ratio = 3)

Specify colour factor

makeBMIplot(sample_n(demo_data,100),
            colFactor="Gender")

Don't specify colour factor

makeBMIplot(sample_n(demo_data,100),
            alpha=0.3)

Add jitter and alpha to counteract overplotting

makeBMIplot(demo_data,
            weight="Weight",
            height="Height",
            colFactor="Gender",
            aspect_ratio = 3,
            jitter=TRUE,
            alpha=0.4)
