Use the binconf() function
binconf() function is available in the Hmisc package. To install this package run the following commands:
install.packages("Hmisc")
Syntax of binconf():
Syntax: binconf(x, n, alpha)
where
- x is the input variable
- n is the sample size
- alpha is the binomial confidence level
R
# load the librarylibrary(Hmisc)# calculate for 34 with 95%confidence levelprint(binconf(x=34, n=100, alpha=.05)) |

How to Calculate a Binomial Confidence Interval in R?
In this article, we will discuss how to calculate a Binomial Confidence interval in R Programming Language. We can calculate Binomial Confidence Interval by using the below formulae:
p +/- z*(√p(1-p) / n)
where,
- p is for the proportion of successes
- z is the chosen value
- n is the sample size
We can calculate by using the below methods
