addMissing {polySegratio}

Adds missing data to objects of class autoMarker or autoCross

Description

Adds missing data to objects of class simAutoMarkers or simAutoCross as specified either as a proportion of missing at random or a proportion of columns and rows with specified proportions of missings.

Usage

addMissing(x, na.proportion = 0, parent.cols = c(1, 2), seed)

Arguments

x

object of class simAutoMarkers or simAutoCross, or a matrix with dominant markers scored as 0 or 1

na.proportion

proportion missing at random or a list with two components indiv and marker each containing c(prop. markers missing, prop. missing) (Default: 0)

parent.cols

columns containing parental markers (etc) not altered only used if object of class simAutoCross

seed

random number generator (RNG) state for random number which will be set at start to reproduce results

Value

Returns object of class simAutoMarkers or simAutoCross, or a matrix with dominant markers scored as 0 or 1 with extra component na.proportion which has the following elements

na.proportion

proportion missing at random or a list with two components indiv and marker each containing c(prop. markers missing, prop. missing)

time.generated

time/date when data set generated + when missing added

seed

random number generator seed which could be used to reproduce results (I hope)

call

matches arguments when function called

Examples

## simulate autopolyploid markers
p1 <- sim.autoCross(4, dose.proportion=c(0.7,0.3), n.markers=20, n.indiv=10)
p2 <- sim.autoCross(4, dose.proportion=list(p01=c(0.7,0.3),p10=c(0.7,0.3),p11=c(
0.6,0.2,0.2)))

## add missings
addMissing(p2, 0.1)
