In reyzaguirre/st4gi: Statistical tools for genetic improvement

Check frequencies

Description

This function cheks the frequencies of valid cases for treatments and replications.

Usage

ck.fq(trait, factors, rep, dfr)

Arguments

trait	The name of the column for the trait to analyze.
factors	The names of the columns that identify the factors.
rep	The name of the column that identifies the replications, NULL for a CRD.
dfr	The name of the data frame.

Value

A table of frequencies of valid cases for all factors' levels combinations (tf), a table of frequencies of valid cases for all factors' levels and replications combinations (tfr), the number of missing values nmis, and the proportion of missing values (pmis).

Examples

## Example 1
# Create a design
dfr <- cr.rcbd(1:20, 3, 10)
dfr <- dfr$book
# Create some random data
dfr$y <- rnorm(60)
# Delete some values
dfr[c(1, 5, 16, 17), 'y'] <- NA
# Check the frequencies
ck.fq("y", "geno", "block", dfr)

## Example 2
# Create a design
A <- paste0("a", 1:5)
B <- paste0("b", 1:3)
dfr <- cr.f(c("A", "B"), list(A, B), "rcbd", 3, 10)
dfr <- dfr$book
# Create some random data
dfr$y <- rnorm(45)
# Delete some values
dfr[c(5, 10, 24), 'y'] <- NA
# Check the frequencies
ck.fq("y", c("A", "B"), "block", dfr)
