I tried all sorts of cex options as I found in help, they do not alter thickness of lines of pie() plot.
x <- c(21, 62, 10, 53)
labels <- c("London", "New York", "Singapore", "Mumbai")
pie(x, labels, main = "City pie chart", col = rainbow(length(x)))
#same as:
pie(x, labels, main = "City pie chart", cex.line=100, col = rainbow(length(x)))
How can I alter thickness of lines in pie()?
