Error in polygon(polar2Cartesian(d2), ...) : plot.new has not been called yet

Hi:
Thanks for the nice package!
When I run the code in chapter 1:

set.seed(999)
n = 1000
df = data.frame(sectors = sample(letters[1:8], n, replace = TRUE),
    x = rnorm(n), y = runif(n))
library(circlize)
circos.par("track.height" = 0.1)
circos.par("points.overflow.warning" = FALSE)
circos.initialize(df$sectors, x = df$x)
circos.track(df$sectors, y = df$y,
    panel.fun = function(x, y) {
        circos.text(CELL_META$xcenter, 
            CELL_META$cell.ylim[2] + mm_y(5), 
            CELL_META$sector.index)
        circos.axis(labels.cex = 0.6)
})

I got this error:

Error in polygon(polar2Cartesian(d2), ...) :
plot.new has not been called yet

How should I fix it? Thanks a lot

I am sorry, I found I have to run all the code together in the same Chunk in Rmd file. Then there is no error anymore.
Thanks
