karyoploteR - An R/Biocondutor package to plot arbitrary data along the genome

Description

karyoploteR is an R package to plot data along the genome using a karyotype style plot.

It is entirely based on R base graphics and inspired by the R base graphics API. It includes functions to plot primitive graphic elements such as points, lines, rectangles, text, etc mapped into the genome plot coordinates and higher level functions to plot a heatmap, the regions in a GenomicRanges object or the cumulative coverage of such regions.

Data positioning and track configuration has been inspired by Circos and does not explicitly understands the concept of track. Thus, it is possible to freely specify where to plot the data and to create plots with multiple independent tracks or overlapping representations.

It is highly configurable and in addition to the parametrization of the different data plotting functions, it is possible to specify custom functions for every plotting action from the basic chromosome bands to the chromosome labels or base numbers as well as creating completely new plotting functions.

How to use it

Documentation (vignette and user manual) is available at the karyoploteR's Bioconductor landing page at http://bioconductor.org/packages/karyoploteR
