dlmap (version 1.13)

data access: Data summaries of dlcross and dlmap objects

Description

Access the number of unique genotyped individuals; unique phenotyped individuals; and number of markers on each map chromosome

Usage

ngen(object, ...)
"ngen"(object, ...)
"ngen"(object, ...)
nphen(object, ...)
"nphen"(object, ...)
"nphen"(object, ...)
nmrk(object, ...)
"nmrk"(object, ...)

Arguments

object

Object of type dlcross or dlmap

...

Additional arguments

Value

ngen returns the number of unique genotyped individuals. nphen returns the number of unique phenotyped individuals - generally greater than or equal to ngen because of replicates. nmrk returns a vector indicating the number of markers on each chromosome.

Examples

# load dataset
data(BSdat)
data(BSphe2)

## Not run: 
# # convert data to dlmap format
# dl.in1 <- dlcross(format="rqtl", genobj=BSdat, idname="ID", fixpos=1)
# 
# ngen(dl.in1)
# nphen(dl.in1)
# nmrk(dl.in1)
# 
# # convert data with separate phenotypic trait file
# dl.in2 <- dlcross(format="rqtl", genobj=BSdat, pheobj=BSphe2, idname="ID", step=5)
# 
# ngen(dl.in2)
# nphen(dl.in2)
