Examples

##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,

## The function is currently defined as
function (x, tr = 0.2, alpha = 0.05, null.value = 0, pr = TRUE) 
{
    library(MASS)
    x <- elimna(x)
    se <- sqrt(winvar(x, tr))/((1 - 2 * tr) * sqrt(length(x)))
    trimci <- vector(mode = "numeric", length = 2)
    df <- length(x) - 2 * floor(tr * length(x)) - 1
    trimci[1] <- mean(x, tr) - qt(1 - alpha/2, df) * se
    trimci[2] <- mean(x, tr) + qt(1 - alpha/2, df) * se
    test <- (mean(x, tr) - null.value)/se
    sig <- 2 * (1 - pt(abs(test), df))

        term = sqrt(area(dnormvar, qnorm(tr), qnorm(1 - tr)) + 
            2 * (qnorm(tr)^2) * tr)
