I have created the below function for Em two binomial mixture and i want to plot the log(theta) versus theta of each iteration but i don't know how to do it?Any help i will appreciate it.

```
EMflipcoin = function(p,n,theta1,theta2,x) {
tol=10^(-10)
maxiter=100
diff=1
iter=0
while(diff>tol & iter<maxiter){
theta1 = theta1
theta2 = theta2
p=p
## E-step:
a = (theta1^x)*(1-theta1)^(n-x);a
b = (theta2^x)*(1-theta2)^(n-x);b
pa = a/(a+b);pa
pb = b/(a+b);pb
eah = pa*x;eah
eat = pa*(n-x);eat
ebh = pb*x;ebh
ebt = pb*(n-x);ebt
c = dbinom(x,n,p);c
c2 = dbinom(x,n,1-p);c2
pc = c/(c+c2);pc
## M-step:
theta1new = sum(eah)/(sum(eah)+sum(eat));theta1new
theta2new = sum(ebh)/(sum(ebh)+sum(ebt));theta2new
pnew = mean(pc);pnew
## calculate diff for tolerance in while condition
diff = (pnew-p)^2+(theta1new-theta1)^2+(theta2new-theta2)^2
iter =iter+1;
theta1 = theta1new
theta2 = theta2new
p =pnew
cat("Iter", iter,
", theta1=",theta1new,
", theta2=",theta2new,
", p =",pnew,
", diff=", diff, "\n")}
}
x=c(5,9,8,4,7)
EMflipcoin(p=0.5,n=10,theta1=0.7,theta2=0.4,x=x)
```
