I am trying to increase the thickness of a single radial axis on my radar chart. In this instance, I want to make my radial axis that has a value 0 thicker than other radial axes. I have highlighted the image below
install.packages('fmsb')
library(fmsb)
max_val = rep(2,26)
min_val = rep(-1,26)
z_score = rep(1,26)
df1 = data.frame(max_val, min_val, z_score)
final_df = data.frame(t(df1))
radarchart(final_df[, c(1,26:2)], seg = 15, axistype = 1,
caxislabels = c(-1,-0.8,-0.6,-0.4,-0.2,
0, 0.2,0.4,0.6,0.8,
1.0,1.2,1.4,1.6,1.8,2))
