Enumeration AmbientStateAccessTypeConst

closes a device (or all of them), returning to the state of another open device

draws from the random number generator, which reads its state and advances it, like runif

getOption(x): reads the option named by the first argument

getwd(): reads the working directory

opens a device, which starts with a fresh graphics state

textConnection(object, open): opened for writing, it binds the variable object names to what is written to it

reads a file, like read.csv, so it sees what was written to the files before

reads the graphics state and the palette, like every plot does

reads the given options, like cat reads digits (see AmbientStateAccess#dispatchOn for print)

reads a state without entries, like search() reads the search path

reg.finalizer(e, f): registers f to run once e is released

gc(): may run every registered finalizer whose object is released

writes the graphics state, unless all arguments are unnamed strings (see AmbientStateAccess#queryOnUnnamedStrings)

sets entries of a keyed state, like Sys.setenv(A = "1") sets the environment variable A, see AmbientKeys

options(...): named arguments set options, unnamed strings query them, anything else sets unknown options

writes the palette, which all devices share; without arguments it only reads it

sets the state of the random number generator, like set.seed, and its kind from the arguments at AmbientStateAccess#kindFrom on

sets a state without entries, like sink(file) diverts the output

setwd(dir): changes the working directory, returning the previous one

makes another open device the active one

writes a file, like write.csv
