The chartbox package stores empty Dutch growth charts. With the package you can
- list the available growth charts;
- set the color palette;
- load one of the growth charts for further processing.
Installation
The following statements will install the chartbox package
install.packages("remotes")
remotes::install_github("growthcharts/chartbox")Example
The load_chart() function makes the stored growth charts available for further processing. Here’s an example that writes chart PJAAN25 to a PDF file.
library(chartbox)
# choose and load chart
chartcode <- "PJAAN25"
g <- load_chart(chartcode)
# set the correct color palette
pop <- chartcatalog::parse_chartcode(chartcode)$population
old_pal <- palette(palettes[pop, ])
# create the pdf
pdf(paste(chartcode, "pdf", sep = "."), height = 29.7/2.54, width = 21/2.54)
grid::grid.draw(g)
dev.off()
#> quartz_off_screen
#> 2
# restore palette
palette(old_pal)
