Compute mean values with confidence intervals
# S3 method for default
ci.mean(x, alpha = 0.05, normal = TRUE, na.rm = TRUE,
statistic = "arithmetic", ...)numeric vector
level of significance
If TRUE use quantile of t-distribution else use normal approximation and quantile of normal approximation. Do you think this is confusing?
If TRUE remove missing values from x.
Decide which mean to compute: either "arithmetic" or "geometric"
