Split a population of genotypes randomly into several locations.

Source: R/fct_split_families.R
split_families.Rd

Split a population of genotypes randomly into several locations, with the aim of having approximatelly the same number of replicates of each genotype, line or treatment per location.

Usage

split_families(l = NULL, data = NULL)

Arguments

l

Number of locations.

data

Data frame with the entry (ENTRY) and the labels of each treatment (NAME) and number of individuals per family group (FAMILY).

Value

A list with two elements.

  • rowsEachlist is a table with a summary of cases.

  • data_locations is a data frame with the entries for each location

Examples

# Example 1: Split a population of 3000 and 200 families into 8 locations. 
# Original dataset is been simulated.
set.seed(77)
N <- 2000; families <- 100
ENTRY <- 1:N
NAME <- paste0("SB-", 1:N)
FAMILY <- vector(mode = "numeric", length = N)
x <- 1:N
for (i in x) { FAMILY[i] <- sample(1:families, size = 1, replace = TRUE) }
gen.list <- data.frame(list(ENTRY = ENTRY, NAME = NAME, FAMILY = FAMILY))
head(gen.list)
#>   ENTRY NAME FAMILY
#> 1     1 SB-1     18
#> 2     2 SB-2     45
#> 3     3 SB-3     69
#> 4     4 SB-4     57
#> 5     5 SB-5     37
#> 6     6 SB-6     29
# Now we are going to use the split_families() function.
