The syntax to draw pie chart in R Programming is pie (x, labels = names (x), col = NULL, main = NULL) and the complex syntax behind this pie chart is: pie (x, labels = names (x), edges = 200, radius = 0.8, clockwise = FALSE, init.angle = if (clockwise) 90 else 0, density = NULL, angle = 45, col = NULL, border = NULL, lty = NULL, main = NULL,..)
