Compute mean values with confidence intervals
# S3 method for default
ci.mean(
x,
alpha = 0.05,
normal = TRUE,
na.rm = TRUE,
statistic = "arithmetic",
...
)
a list with mean values and confidence limits
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"
