make_glyphs_draw: Make glyphs in different classes

In rwoldford/glyphs: Make glyphs using pixel-oriented data visualization technique

Description

Given a list of data vectors, make a corresponding list of glyphs in one of four different classes which are "png", "jpeg", "pixmap" and "tiff".

Usage

make_glyphs_draw(
  data,
  draw_fun,
  type = c("png", "jpeg", "pixmap", "tiff"),
  width = 50,
  height = 50,
  mar = rep(1, 4),
  ...
)

Arguments

data	a list of data vectors
draw_fun	function of drawing in a device given a data vector
type	string specifying the format of output. "png" means the output is a list of data matrices in the png format, "jpeg" means the output is in the jpeg format and so on.
width	the width of the device
height	the height of the device
mar	A numerical vector of the form c(bottom, left, top, right) which gives the number of lines of margin to be specified on the four sides of the plot
...	Arguments passed to 'png', 'jpeg', 'pixmap', or 'tiff' according to the 'type'

Value

a list of glyphs in different classes corresponding to the list of data

Examples

n <- 16
data <- list()
for (i in 1:n){
  data[[i]] <- rnorm(500)
}
glyphs <- make_glyphs_draw(data, hist, type = "jpeg", mar = rep(4, 4), width = 200, height = 200)
x <- getGridXY(n)
plot_glyphs(x, glyphs = glyphs, glyphWidth = 0.8, glyphHeight = 0.6, axes = FALSE, xlab = "", ylab = "")
