Dear R developers, I found a small issue while plotting contours of data containing both "usual" and "very small" numbers. It appeared with both R 3.0.1 and R-Devel on Windows, and I could reproduce it on Linux. Would it be possible to solve this before the upcoming release?
Thanks a lot for developing this great software! Thomas Example: ######## set.seed(357) z1 <- matrix(runif(100, -1e-180, 1e-180), nrow = 10) contour(z1) # ok z2 <- matrix(c(runif(50, -1, 1), runif(50, -1e-180, 1e-180)), nrow = 10) contour(z2) # Error in contour.default(z) : k != 2 or 4 contour(z2 * 1e20) # 20 worked, 19 produced error contour(round(z2, 179)) # rounding to 179 digits works but not 180
