Plot the locations of the QTL against a genetic map
## S3 method for class 'qtl':
plot(x, chr, horizontal=FALSE, shift=TRUE,
show.marker.names=FALSE, alternate.chrid=FALSE, ...)
x |
An object of class "qtl", as produced by
makeqtl. |
chr |
Optional vector indicating the chromosomes to plot.
This should be a vector of character strings referring to chromosomes
by name; numeric values are converted to strings. Refer to
chromosomes with a preceding - to have all chromosomes but
those considered. A logical (TRUE/FALSE) vector may also be used. |
horizontal |
Specifies whether the chromosomes should be plotted horizontally. |
shift |
If TRUE, shift the first marker on each chromosome to be at 0 cM. |
show.marker.names |
If TRUE, marker names are included. |
alternate.chrid |
If TRUE and more than one chromosome is plotted, alternate the placement of chromosome axis labels, so that they may be more easily distinguished. |
... |
Passed to plot.map. |
Creates a plot, via plot.map, and indicates the
locations of the QTL in the input QTL object, x.
None.
