Hi , Thanks for reply
My latitude and longitude contains 90000-100000 observations per file when I run coords <- expand.grid(lat=1:5,long=1:5) then my computer *** caught segfault *** address 0x6951c20, cause 'memory not mapped' Traceback: 1: .C("spline_eval", z$method, nu = as.integer(n), x = as.double(xout), y = double(n), z$n, z$x, z$y, z$b, z$c, z$d, PACKAGE = "stats") 2: spline(gam.data$x[, col.data], gam.smooths.all$fit[, m], xout = gam.results.global[m, , "x.values"], ties = mean) 3: eval.with.vis(expr, envir, enclos) 4: eval.with.vis(ei, envir) 5: source(file.path(getwd(), "Skripte", "r", "GAM_hourly", "1_calcs_GAM_all_sites_hourly.R"), echo = TRUE, max.deparse.length = 2e+05) Possible actions: 1: abort (with core dump, if enabled) 2: normal R exit 3: exit R without saving workspace 4: exit R saving workspace so is there any other way to deal with this ? My main objective to plot this observations on global map the sample data is lat <- -11.3082 -11.6041 -11.9002 -12.1961 -12.1461 -12.7881 -12.6657 -12.8467 -13.7233 -13.6271 lon<- 135.6423 135.5799 135.5184 135.4558 133.5313 135.3321 134.6688 133.9839 132.0651 131.5528 gas <- 1688.91 1679.24 1677.77 1635.60 1652.77 1663.43 1642.16 1671.84 1674.65 1665.54 -- View this message in context: http://r.789695.n4.nabble.com/Plotting-function-image-tp4387796p4389959.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list 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.
