print(x, ...)

## S3 method for class 'linkres'
summary(object, ...)

## S3 method for class 'linkres'
as.data.frame(x, ..., sort = TRUE)

## S3 method for class 'linkres'
plot(x, chrom = NULL, ylim = NULL, ...)

Arguments

x, object

a linkres object (normally produced by lod or merlin).

...

further arguments.

sort

a logical, indicating if the data frame should be sorted according to map position.

threshold

a single numeric. A peak is defined as a regions of at least width consecutive markers LOD score above threshold.

width

a single numeric.

physmap

a matrix or data frame with three columns: Marker name, chromosome and physical position. This argument is optional.

chrom

NULL, or a numeric containing chromosome numbers. In the latter case only results for the markers on the indicated chromosomes will be plotted.

ylim

NULL, or a numeric of length 2: to be passed on to plot.default.
