fn_freq

Description

The interval and class mark are defined and the absolute, cumulative and relative cumulative frequency is calculated in a table.

It returns a table with the absolute, cumulative and relative cumulative frequency by interval and class mark.

The function requires defining:

• df: A data frame array.
  
• Imin: Minimum value to be defined for the x-axis.
• Imax: Maximum value to be defined for the x-axis.
• bin: A bin value to define the width of the class interval.

fn_freq

The function is included in the Repbio package Reproductive biology analysis.

#library(Repbio)

The function is detailed below.

fn_freq <- function(df, Imin, Imax, bin){
                  breaks<- seq(Imin, Imax, bin)
                  tmp.cut <- cut(df,breaks, right=FALSE)
                  fre = table(tmp.cut)
                  cum <- cumsum(fre)
                  frc <- cum/max(cum)
                  MCmin <- Imin+(bin/2)
                  MCmax <- Imax-(bin/2)
                  MC<- seq(MCmin,MCmax,bin)
                  cbind(MC,fre,cum,frc)
}   # End function

Examples

Falta detallar el ejemplo. This is an example … . The immatures are excluded from the analysis, giving them a value of zero.

    # df <- tmp
    # Imin <- 1
    # Imax <- 30
    # bin <- 1
    # ejemplo <-  fn_freq(df, Imin, Imax, bin)
