The function calculates a frequency distribution of data using the functions:
`cut()` and `table()` from the R base.
Usage
fn_freq(df, breaks, right = FALSE)
Arguments
- df
A vector of data values.
- breaks
A vector with class intervals.
- right
Logical, indicating if the intervals should be closed on the right (and open on the left) or vice versa.
Value
A table with frequencies by class interval is returned.
Details
Inside the function:
The non-cumulative absolute frequency is calculated for each user-defined
class interval within the `breaks` object.
The `breaks` object must be defined outside the function by the user. For
example a sequence of breakpoints of equal distance could be used.

Examples
# In the df object, 30 random values between 0.1 and 0.9 are generated.
# The breaks object is a sequence of equal distances.
if (FALSE) { # \dontrun{
df <- runif(n=30, min=0, max=1)
breaks <- seq(0, 1, by= 0.1)
freq <- fn_freq(df, breaks, right= FALSE)
} # }
