## LDheatmap <img src="man/figures/logo.png" align="right" />
`LDheatmap()` is used to produce a graphical display,
as a heat map, of pairwise linkage disequilibrium (LD)
measurements for SNPs.
The heat map is a false color image in the upper-left
diagonal of a square plot. A line parallel to
the diagonal of the image indicating
the physical or genetic map positions of the SNPs
may be added, along
with text reporting the total length of the genomic
region considered. Users may also display the heatmap
"flipped" below a horizontal line indicating the map
positions of the SNPs. In this orientation,
tracks may be added above the genetic map.
## Installation
```{r,eval=FALSE}

# imported/suggested BioConductor packages with
install.packages("LDheatmap")
source("https://bioconductor.org/biocLite.R")
biocLite(c("snpStats","rtracklayer","GenomicRanges","GenomInfoDb","IRanges"))
# Install the latest development version from GitHub with
