cutBySD: Returns center values of x, the mean, mean-std.dev, mean+std.dev

Description

If the numeric variable has fewer than 6 unique observed values, this will send the data to cutByTable.

Usage

cutBySD(x, n = 3)

Arguments

x

A numeric variable

n

Should be an odd number 1, 3, 5, or 7. If 2 < n < 5, values that divide the data at c(m-sd, m, m+sd) are returned. If n > 4, the returned values are c(m-2sd, m-sd, m, m+sd, m+2sd).

Value

A named vector

Examples

# NOT RUN {
x <- rnorm(100, m = 100, s = 20)
cutBySD (x, n = 3)
cutBySD (x, n = 5)
# }
