[R] Unusual graph- modified wind rose perhaps?

[ONKELINX, Thierry]

Dear John,

You can get pretty close with ggplot2.

Best regards,

Thierry

library(ggplot2)
dataset <- data.frame(Name = LETTERS[1:26])
dataset$Score <- runif(nrow(dataset))
dataset$Category <- cut(dataset$Score, breaks = c(-Inf, 0.33, 0.66, Inf), labels = c("Bad", "Neutral", "Good"))
dataset$Name <- factor(dataset$Name, levels = dataset$Name[order(dataset$Score)])
dataset$Location <- as.numeric(dataset$Name)

ggplot(dataset, aes(x = Name, y = Score, fill = Category)) + geom_bar() + coord_polar()


#with some extra tweeking
dataset <- rbind(dataset, 
	data.frame(
		Location = c(max(dataset$Location) + seq_len(max(dataset$Location) / 2), min(dataset$Location) - seq_len(max(dataset$Location) / 2)),
		Name = "",
		Score = 0,
		Category = "Good"
	)
)
ggplot(dataset, aes(x = Location, y = Score, fill = Category)) + geom_bar(stat = "identity") + coord_polar(start = pi, direction = -1) + scale_fill_manual(value = c(Good = "green", Neutral = "grey", Bad = "red")) + theme_bw() + scale_x_continuous("", breaks = dataset$Location, labels = dataset$Name)

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.
~ John Tukey
