PolyHaplotyper (version 1.0.1)

read.ShesisPlus.output: Read the haplotyping results from the ShesisPlus output

Description

Read the haplotyping results from the ShesisPlus output

Usage

read.ShesisPlus.output(SSPout, order.by=c("", "hapnr", "count")[2])

Arguments

SSPout

filename of a text file with ShesisPlus output (as copied from the web page produced by running ShesisPlus web interface at http://shesisplus.bio-x.cn/SHEsis.html); or a character vector with the same output

order.by

how to order the rows of the hapstat data.frame. "hapnr" means ordering by haplotype number, "count" means ordering by decreasing Total.count, anything else results in no reordering. By default order by hapnr.

Value

a list with 2 items: $markernames has the marker names in the markers in the haploblock (if present in the file); hapstat contains the haplotype statistics as read from the file with an additional (first) column hapnr: the haplotype numbers as defined in PolyHaplotyper. The other columns are Haplotype (as sequences of marker alleles), Total.count (of the haplotype over the whole population) and, according to an email from Zhiqiang Li of 13-04-2020) BETA: Regression coefficient, SE: Standard error, R2: Regression r-squared, T: t-distribution statistics, P: p-value

Details

If present, the markernames and the haplotype statistics are read from the file. ShesisPlus does not provide haplotype combinations for individuals

Examples

# NOT RUN {
# we give a typical SSP output as character vector; instead we could also
# give the name of a text file
