ggradar

This ggradar is modified from the ggradar, which allows you to build radar charts with multiple gridline.

Install ggradar

devtools::install_github("1156054203/ggradar", 
                          dependencies = TRUE)

Use ggradar

library(ggradar)
library(dplyr)
library(scales)
library(tibble)

set.seed(21)
sampleA <- sample(seq(1,23),size=23)
sampleB <- sample(seq(1,23),size=23)
data <- data.frame(group=c('sampleA','sampleB'),
                   t(data.frame(sampleA=sampleA,sampleB=sampleB)))
chroms <- paste0('chr',c(seq(1:22),'X'))
colnames(data)[-1] <- chroms

	group	chr1	chr2	chr3	chr4	chr5	chr6	chr7	chr8	chr9
sampleA	sampleA	19	6	15	4	23	17	2	3	21
sampleB	sampleB	22	7	17	12	15	13	20	19	8

ggradar2(data,all.radar=seq(1:23),axis.label.size=3.5,grid.label.size=4,group.point.size=1,
         group.line.width=0.6, legend.position='right')

Custom config

In addition to all.radar and all.label, other parameters are consistent with the original package ggradar.
Note:
all.radar: vector, each value is used to specify the gridline.
all.label: vector, each value is used to specify the label for gridline, default is value of all.radar.
gridline.min.linetype: used to specify gridline style.
gridline.min.colour: used to specify gridline colour.
