[R] Estimates for proportions

[Tanya Murphy]

Hello,

I need to get a point estimate and SD for a proportion, but the subjects' data 
are not binary---they are proportions (of doses received). That is, I have a 
proportion for each subject. In the past I have analysed these data as a 
continuous (normal) variable, but I really don't want CIs over 100%. This 
seems like basic stuff, but I don't remember learning it and it's proving 
difficult to find (in medical statistics texts, anyway). Any pointers would be 
greatly appreciated!

Thanks!
