Usage
saveMovie(expr, interval=1, moviename="animation.gif", loop=0, dev=png,
filename="Rplot", fmt="%03d", fileext="png", outdir=getwd(),
convert="convert", cmd.fun, clean=TRUE, ani.first,
para=par(no.readonly = TRUE), ...)Arguments
expr
an expression to generate animations; use either the animation
functions (e.g. brownian.motion()) in this package or a custom
expression (e.g. for(i in 1:10) plot(runif(10), ylim = 0:1)).
interval
duration between animation frames (unit in seconds)
moviename
file name of the movie (with the extension)
loop
iterations of the movie; set iterations to zero to repeat the
animation an infinite number of times, otherwise the animation repeats
itself up to loop times (N.B. for GIF only!)
dev
a function for a graphical device such as
png, jpeg and
bmp, etc. filename
file name of the sequence of images (`pure' name; without
any format or extension)
fmt
a C-style string formatting command, such as %3d
fileext
the file extensions of the image frames
outdir
the directory for the movie frames
convert
the ImageMagick command to convert images (default to be
convert, but might be imconvert under some Windows
platforms); see the 'Note' section for details
cmd.fun
a function to invoke the OS command; by default,
shell under Windows and system under other OS clean
whether to delete the individual image frames
ani.first
an expression to be evaluated before plotting (this will
be useful to set graphical parameters in advance, e.g. ani.first =
par(pch = 20)
para
a list: the graphics parameters to be set before plotting;
passed to par; note ani.first can override
this argument ...
other arguments passed to the graphical device, such as
height and width, ...
