matlab - Animation in R without saving figures and without external software -

is possible create animation in r directly, in matlab, without saving figures , using external software? executing script?

consider following example in matlab.

t = (1:360) / 180 * pi;    % 360 angles in radians 1 360 degrees n = length(t);    % length of vector x = cos(t);    % cosines y = sin(t);    % sines f = figure;    % create figure , handle hh = plot(2, 2, 'or', 'markerfacecolor', 'r', 'markersize', 10);    % create plot , handle set(gca, 'xlim', [-1 1]);    % set x axis limits set(gca, 'ylim', [-1 1]);    % set y axis limits axis square; axis off;    % set more properties axes  while ishandle(f)    % until user closes figure   try    % try loop, if encouter error break loop     ii = 1:n    % angles       set(hh, 'xdata', x(ii))    % change point x coordinate       set(hh, 'ydata', y(ii))    % change point y coordinate       pause(0.01)    % make little pause     end   end end

after hrbrmstr's answer, have tried this:

t <- (1:360) / 180 * pi n <- length(t) x <- cos(t) y <- sin(t)  while(true) {   (i in 1:n) {     plot(x[i], y[i], ann=false, pch=20, axes=false, xlim=c(-1, 1), ylim=c(-1, 1), col="red", cex=4, asp=1)     sys.sleep(0.01)   } } 

and seems doing job. thanks!

i have tried this:

t <- (1:360) / 180 * pi n <- length(t) x <- cos(t) y <- sin(t)  while(true) {   (i in 1:n) {     plot.new()     usr<-par("usr")     par(usr=c(-1.1, 1.1, -1.1, 1.1))     lines(x, y, col="green")     points(x[i], y[i], pch=20, col="red", cex=4, asp=1)     sys.sleep(0.01)   } } 

which closer had in mind. find r's "paper , pen" drawing model terrible. isn't there way around that?

i'm not try figure out matlab plotting doing w/r/t aesthetics.

this:

while(true) {   barplot(sample(1:1000, 10))   sys.sleep(0.5) } 

"animates" random bar chart display pretty imo and:

t <- (1:360) / 180 * pi n <- length(t) x <- cos(t) y <- sin(t)  (i in 1:n) {   plot(x[1:i], y[1:i], type="p")   sys.sleep(0.15) } 

does 1 basic bit of "animation" of points in 1 fashion and:

for (i in 1:n) {   plot.new()   points(x[1:i], y[1:i])   sys.sleep(0.15) } 

in (though 1 needs work setting x & y limits avoid graphics device errors).

all 3 stop when asked "stop" gui or when for loop done.

not "disproportionately complex". more "not familiar matlab person".
