[英]how to increase the radius in circlize plot
I have drawn the following plot using the circlize
package.我使用
circlize
包绘制了以下图。 The red circle is the unit circle drawn afterwards, using plotrix
.红色圆圈是之后绘制的单位圆,使用
plotrix
。 I want to plot the first track outside the red unit circle.我想绘制红色单位圆外的第一条轨道。 For this reason I changed
canvas.xlim
and canvas.ylim
to c(-1.2, 1.2)
.出于这个原因,我将
canvas.xlim
和canvas.ylim
更改为c(-1.2, 1.2)
。 However, this does not work.但是,这不起作用。 Any ideas how to increase the circle radius for the
circlize
plot?任何想法如何增加对圆半径
circlize
情节?
NOTE : Alternatively, it would be sufficient for me, if the tracks would be outside of the unit circle instead of inside.注意:或者,如果轨道位于单位圆之外而不是内部,则对我来说就足够了。
library(circlize)
set.seed(2)
n = 10
a = data.frame(factor = "dummy",
x = rnorm(n, 100, sd=10))
circos.par(track.height = 0.2,
canvas.xlim=c(-1.2, 1.2), # bigger canvas?
canvas.ylim=c(-1.2, 1.2)) # bigger canvas?
circos.initialize(factors = a$factor,
x = a$x, xlim = c(0, 360))
lim <- c(-1.2, 1.2)
plot(NULL, asp=1, xlim=lim, ylim=lim)
circos.trackHist(a$factor, a$x, col = "blue", bg.col = grey(.95))
plotrix::draw.circle(0,0,1, border="red", lwd=2) # unit circle
I don't know how to adjust xlim
and ylim
to make two plots fit.我不知道如何调整
xlim
和ylim
以使两个图适合。 But if you just want to put the red circle inside the track, you can use draw.sector()
function directly:但是如果你只是想把红色圆圈放在轨道里面,你可以直接使用
draw.sector()
函数:
circos.initialize(factors = a$factor,
x = a$x, xlim = c(0, 360))
circos.trackHist(a$factor, a$x, col = "blue", bg.col = grey(.95))
draw.sector(0, 360, rou1 = circlize:::get_most_inside_radius(),
border = "red")
Here circlize:::get_most_inside_radius()
returns the distance between the bottom border of the last track to the center of the circle.这里
circlize:::get_most_inside_radius()
返回最后一条轨道的底部边界到圆心的距离。
