Saves Graphical Output with plot capture capability

Description

Closes all graphical devices with dev.off() and saves the output only if both fileName and type are provided. Enhanced version that can capture plots before closing devices.

Usage

saveGraphVisstat(
  fileName = NULL,
  type = NULL,
  fileDirectory = getwd(),
  oldfile = NULL,
  capture_env = NULL
)

Arguments

fileName	name of file to be created in directory fileDirectory without file extension '.type'.
type	see Cairo().
fileDirectory	path of directory, where graphic is stored. Default setting current working directory.
oldfile	old file of same name to be overwritten
capture_env	Environment to store captured plots. If NULL, no capture occurs.

Value

NULL, if no type or fileName is provided, file path if graph is created

Examples

# very simple KDE (adapted from example in Cairo())
openGraphCairo(type = "png", fileDirectory = tempdir())
plot(rnorm(4000), rnorm(4000), col = "#ff000018", pch = 19, cex = 2)
# save file 'norm.png' in directory specified in fileDirectory
saveGraphVisstat("norm", type = "png", fileDirectory = tempdir())
file.remove(file.path(tempdir(), "norm.png")) # remove file 'norm.png'
