Plotting confidence intervals from a dataframe

I have written some R code which produces the limits of confidence intervals as well as the information if each confidence interval covers the true parameter. I'd like to visualize this but have no idea how.

confInt <- function(runs){
    result<-NULL
    vleft<-NULL
    vright<-NULL

    for (i in 1:runs) {
        data<-rnorm(1000)
        n<-length(data)
        a<-mean(data)
        s<-sd(data)
        error <- qnorm(0.975)*s/sqrt(n)
        left <- a-error
        right <- a+error

        result[i] = left<0 & 0<right
        vleft[i] = left 
        vright[i] = right
}
    data.frame(result,vleft,vright)
}


confInt(100)
