scatterplot {DALY}

Scatterplot method for class 'DALY' and 'DALY_list'

Description

Generate a scatterplot of population versus patient level burden. The method is available for objects of class 'DALY' and 'DALY_list'.

Usage

## S3 method for class 'DALY'
scatterplot(x, plot = c("DALY", "YLD", "YLL"), outcomes = TRUE,
            per = 1000, samples = 1000, pch = 16, col = NULL, legend = NULL,
            legend_pos = c("topright", "topleft", "bottomright", "bottomleft"), ...)

## S3 method for class 'DALY_list'
scatterplot(x, plot = c("DALY", "YLD", "YLL"),
            per = 1000, samples = 1000, pch = 16, col = NULL, legend = NULL,
            legend_pos = c("topright", "topleft", "bottomright", "bottomleft"), ...)

Arguments

x

Object of class 'DALY' or 'DALY_list'

plot

Which estimates should be plotted? Must be either "DALY", "YLD" or "YLL"

outcomes

Should different outcomes be plotted? Defaults to TRUE. If FALSE, aggregated estimates are plotted

per

Denominator for population level burden. Defaults to 1000

samples

Number of samples to plotted. Defaults to 1000

pch

Plotting symbol. Defaults to 16 (= solid circle). See pch for more info

col

Plotting color. Defaults to NULL, in which case the function tries to generate distinctive rainbow colors

legend

A character or expression vector of length \ge 1 to appear in the legend. Defaults to NULL, in which case the legend names are derived from the plotted objects; if FALSE, no legend is plotted

legend_pos

The position of the legend, either "topright", "topleft", "bottomright" or "bottomleft"

...

Additional arguments to be passed to plot

Details

This function generates a scatterplot of the estimated burden at the population level (x-axis) versus the patient level (y-axis). Scatterplots can be generated of 'DALY' objects, to visualize the overall or outcome-specific burden; and of 'DALY_list' objects, to compare the overall burden of, e.g., different diseases or different DALY calculation scenarios.

Examples

## Not run: 

##= load toxoplasmosis example ============================
setDALYexample(2)

##= perform DALY calculation for different scenarios ======
toxo_00 <- getDALY(aw = FALSE, dr = 0)
toxo_03 <- getDALY(aw = FALSE, dr = 0.03)
toxo_13 <- getDALY(aw = TRUE,  dr = 0.03)

##= combine scenarios in 'DALY_list' ======================
toxo <- DALY_list(toxo_00, toxo_03, toxo_13)

##= plot YLL and YLL for toxo_00 ==========================
par(mar = c(4, 4, 1, 1) + .5)
par(mfrow = c(1, 2))
scatterplot(toxo_00, plot = "YLL",
            outcomes = FALSE, legend = FALSE)
scatterplot(toxo_00, plot = "YLD",
            outcomes = FALSE, legend = FALSE)

##= plot all three scenarios ==============================
par(mfrow = c(1, 1))
scatterplot(toxo,
            legend = c("DALY[0,0]",
                       "DALY[0,0.03]",
