被启迪-R画出我的心

先来个正经的图

code

#导包
library(animation)
#注释一下，生成gif会使用到ImageMagick软件自己上网上找。
#如果出现convert: 455: unable to load module`C:\ImageMagick\modules\coders\IM_MOD_RL_PNG_.dll‘
#请下载Microsoft Visual C++ 2008 Redistributable Package，还有就是环境变量的锅了。

t<-seq(0,2*pi,by=0.1)
x<-16*sin(t)^3

a<-(x-min(x))/(max(x)-min(x))
b<-(y-min(y))/(max(y)-min(y))
#gif生成
saveGIF({
  for (i in seq(1,length(a),3)){
    sch<-a[1:i]

    plot(sch,u)
  }

来个不正经的图

#code
a1<-seq(0,2,0.01)
b1<-seq(0,1,0.01)
f<-function(a1,b1) ifelse(a1<=1, 11*a1*log10(a1)*b1*(b1-1)+exp(-((25*a1-25/exp(1))^2+(25*b1-25/2)^2)^3)/25, 11*(a1-1)*log10(a1-1)*b1*(b1-1)+exp(-((25*(a1-1)-25/exp(1))^2+(25*b1-25/2)^2)^3)/25) 
c1<-outer(a1,b1,f)
persp(a1,b1,c1,theta=30,phi=30,expand=0.5,col="blue")
