#导入内建人类染色体数据
data(UCSC.HG19.Human.CytoBandIdeogram);
head(UCSC.HG19.Human.CytoBandIdeogram);

chr.exclude <- NULL;                            #设置不显示的染色体，如 c(1,3)
cyto.info <- UCSC.HG19.Human.CytoBandIdeogram; #设置染色体数据
tracks.inside <- 10;                                                       #设置内部track 个数

#导入上面四个基本参数

#列出所有绘图参数
RCircos.List.Parameters()

#Following are an example to change RCircos plot parameters:
#===========================================================

params <- RCircos.Get.Plot.Parameters(); #获得参数列表
params$radius.len <- 2.0;                                   #更改其中的参数
params$base.per.unit <- 5000;                           #更改其中的参数
RCircos.Reset.Plot.Parameters(params)     #参数重置

#定义要生成的图像文件，pdf，png，tiff 等，注意：最后要用dev.off()关闭
out.file <- "D:/RCircosDemoHumanGenome.tiff";
pdf(file=out.file, height=8, width=8, compress=TRUE);
RCircos.Set.Plot.Area();

#Plot Chromosome Ideogram
