R-491个字符
我有点晚了,但是昨天才看到这篇文章。
在Mac上运行,使用playRWave以及package tuneR
和splancs
。
a=array
x=c(7,2)
y=c(5,2)
z=c(1,1,3,3)
par(mar=rep(0,4))
plot(NA,xli=c(0,9),yli=c(0,3))

c=c(NA,NA,NA,1,1)
for(i in 1:5){polygon(N[[i]],c=c[i])}
h=c(261.63,293.66,329.63,277.18,311.13)
library(tuneR)
setWavPlayer("~/Library/Audio/playRwave")
repeat{P=data.frame(locator(1));play(sine(h[sapply(N,function(x)splancs::inout(P,x))],bit=16))}
取消高尔夫:
par(mar=rep(0,4))
plot(NA,xlim=c(0,9),ylim=c(0,3)) #Create empty plot: due to fuzzy matching of arguments, xlim can be reduced to xli
N=list(array(c(0,3,3,2,2,0,0,0,0,1,1,3,3,0),dim=c(7,2)), #C polygon
