Hello, How to map points to a fixed points position, then draw contours to the mapped points?
A data frame like this: r <- rep(seq(0,3.8,0.2), 256) PI257 <- seq(0,360,360/256) PI256 <- PI257[-257] PI25631 <- rep(PI256, 20) El <- rnorm(5120, mean = 42, sd = 4) xyz <- data.frame(r, PI25631, EI) How to map y points to the fixed position defined by x and y in a polar system, using R base plot functions or ggplot2 (aes mapping) to achieve a similar figure like the link: https://www.clspectrum.com/archive/2009/October/images/CLS_October_A10_Fig04.jpg Sincerely yours, [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
