Import data from polymapR

Description

Function to import datasets from polymapR.

Usage

import_data_from_polymapR(
  input.data,
  ploidy,
  parent1 = "P1",
  parent2 = "P2",
  input.type = c("discrete", "probabilistic"),
  prob.thres = 0.95,
  pardose = NULL,
  offspring = NULL,
  filter.non.conforming = TRUE,
  verbose = TRUE
)

Arguments

input.data

a polymapR dataset

ploidy

the ploidy level

parent1

a character string containing the name (or pattern of genotype IDs) of parent 1

parent2

a character string containing the name (or pattern of genotype IDs) of parent 2

input.type

Indicates whether the input is discrete ("disc") or probabilistic ("prob")

prob.thres

threshold probability to assign a dosage to offspring. If the probability is smaller than thresh.parent.geno, the data point is converted to 'NA'.

pardose

matrix of dimensions (n.mrk x 3) containing the name of the markers in the first column, and the dosage of parents 1 and 2 in columns 2 and 3. (see polymapR vignette)

offspring

a character string containing the name (or pattern of genotype IDs) of the offspring individuals. If NULL (default) it considers all individuals as offsprings, except parent1 and parent2.

filter.non.conforming

if TRUE exclude samples with non expected genotypes under no double reduction. Since markers were already filtered in polymapR, the default is FALSE.

verbose

if TRUE (default), the current progress is shown; if FALSE, no output is produced
