Format RadarChart in R (title, subtitle and labels) - r

Question

Here's the data:
df <- data.frame(Jan = 2230, Feb = 2420, Mar = 2833, Apr = 2192, May = 2332, Jun = 2577, Jul = 4363, Aug = 3747, Sep = 3176, Oct = 3988, Nov = 2144, Dec = 1896)
df <- rbind(4363, 0, df)
And here's the code to build the radar chart:
radarchart(df,
pcol = '#B62682', pfcol = alpha("#E1f56E", 0.7), plwd = 2,
axistype = 1, cglcol = "lightgrey", cglty = 1,
axislabcol = "black", cglwd = 1, caxislabels=seq(0, round(max(df[,1]), 0), round(max(df[,1])/8, 0)),
calcex = 1, palcex = 1, vlcex = 1, seg = 7,
title = "Title")
Ideally, I want to change the title's font size, add a subtitle and change the order of the labels (month labels should follow a clockwise direction). If this can't be done using radarchart(), I'm open to use other libraries. With ggplot() it would be super simple using labs() to add a title and subtitle and plot.title, plot.subtitle, etc to format.
Thanks in advance!

Answer 1

Complete answer:
radarchart(df,
pcol = '#B62682', pfcol = alpha("#E1f56E", 0.7), plwd = 2,
axistype = 1, cglcol = "lightgrey", cglty = 1, axislabcol = "black", cglwd = 1,
caxislabels=seq(0, round(max(df[,1]), 0), round(max(df[,1])/8, 0)),
calcex = 1, palcex = 1, vlcex = 1, seg = 7)
mtext(side = 3, line = 2.5, at = 0, cex = 1.75, "Title", font = 2)
mtext(side = 3, line = 1, at = 0, cex = 1.25, "Subtitle", col = '#666664')
line is for the height,
cex works as the size of the text,
at is the position (left - negative or right - positive, 0 center)

Answer 2

The order actually are very simple.
You can just change the order in the data
df <- data.frame(Jan = 2230, Feb = 2420, Mar = 2833, Apr = 2192, May = 2332, Jun = 2577, Jul = 4363, Aug = 3747, Sep = 3176, Oct = 3988, Nov = 2144, Dec = 1896)
df = df[, c(12,11,10,9,8,7,6,5,4,3,2,1)] # change the order
df <- rbind(4363, 0, df)
Insted of this title = "Title" you can use this for the title font size
title=("title", vlcex=0.5)
