  cols = NULL,
  horis = FALSE,
  spacer = 0.1
)

Arguments

centers	coordinates along dimension to be annotated (centers)
labs	list of character vectors of labels or matrix of columns. Each item in the list results in one annotation. List names will be used to label annotation.
cex	width (in lines) of each annotation (0.7 is default)
cols	list of named color vectors specifying colors for each label, should have same length as labs. Generated by char2col if NULL
horis	logical, whether annotation should be horizontal or vertical
spacer	spacer (in lines) between plot and annotation

Examples

par(mgp=c(3,2,1.5))
image(1:5,1:2,matrix(1:10,ncol=2))
plotColorAnn(1:5,list(a1=c(1,1,2,3,3),a2=c('a','b','a,','b','a')),horis=T)
plotColorAnn(1:2,cbind(y1=c(1,2),y2=c('a','a')),horis=F)
