Returns center values of x, the mean, mean-std.dev, mean+std.dev
If the numeric variable has fewer than 6 unique observed values, this will send the data to cutByTable.
cutBySD(x, n = 3)
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). |
