[R] Beta distribution- help needed

[baxy77]

Hi, 

Well, i need some help, practical and theoretical. I am wondering why the
fitdistplus (mle function) is returning an error for this code:

[code]
x1 <- c(100,200,140,98,97,56,42,10,2,2,1,4,3,2,12,3,1,1,1,1,0,0);
plotdist(x1);
descdist(x1, boot =1000);
y<- sum(x1);
d= as.vector(length(x1));
for(i in 1:length(x1)){
  d[i] = x1[i]/y;
}
fitdist(d, "beta")

[/code] 

Error: 

Error in fitdist(d, "beta") : 
  the function mle failed to estimate the parameters, 
                with the error code 100

and what should i do to fix this ??

Thank you
