[R] circlize package: different font size for axis labels

Hi, Dr. Gu,
Thank you very much for the answer. This trick works. 
Another question, is there a way to change the color or the axis?

In current version, `labels.font` in `circos.axis` can only be a scalar ( a vector with length one).
But you can first add axes with no labels and then add labels by `circos.text`:

female.f = c("a", "b")
circos.initialize(factors=female.f, xlim=c(1.8,6.2))
circos.trackPlotRegion(factors=female.f, ylim=c(-1.3,1.8),track.height=0.5, panel.fun=function(x,y) {
        circos.axis(h = "top", major.at=c(2:6),minor.ticks=0,labels= rep("", 5),labels.cex=0.8,major.tick.percentage=0.02,
        circos.text(2:6, rep(1.5, 5), c("L3","72hL3","72hL4","8dF","16dF"), font = c(1, 2, 1, 1, 1), facing = "inside", niceFacing = TRUE)

Hi, Dr. Gu,

I am trying to highlight some axis labels, for example, "72hL3" as bold, using the following command:

circos.initialize(factors=female.f, xlim=c(1.8,6.2))
direction="inside", labels.font=c(1,2,1,1,1,1))})

Is there a way to do this using circlize package?
