By any chance are there any alternatives to image(...) and filled.contour(...)
I used Rseek to search for that very topic, but didn't turn over any leads... http://www.rseek.org/?cx=010923144343702598753%3Aboaz1reyxd4&newwindow=1&q=alternative+to+image+and+filled.contour&sa=Search&cof=FORID%3A11&siteurl=www.rseek.org%252F#1238 I'm sure there are some out there, but curious about some of the favorites and ones folks have had success using. Thanks for any insights and feedback. I would like to use the alternative 2-D fill function with the example I have been messing with in place of image(...) or filled.contour(...): library(akima) hyp_distance<-seq(1,15) angle_deg_val<-seq(0,15) x_distance_val<-NULL y_distance_val<-NULL for(ii in 1:length(hyp_distance)) { for(jj in 1:length(angle_deg_val)) { x_distance_tmp<-hyp_distance[ii]*cos(angle_deg_val[jj]*pi/180) y_distance_tmp<-hyp_distance[ii]*sin(angle_deg_val[jj]*pi/180) x_distance_val<-c(x_distance_val, x_distance_tmp) y_distance_val<-c(y_distance_val, y_distance_tmp) } } temperature_vals<-rnorm(length(x_distance_val), 75, 2) temp_samples<-cbind(x_distance_val, y_distance_val, temperature_vals) temp_samples_DF<-data.frame(x = x_distance_val, y = y_distance_val, z = temperature_vals) ak.fan <- interp(temp_samples[,1], temp_samples[,2], temp_samples[,3] ) length_val<-floor(max(temperature_vals) - min(temperature_vals))*2 color_vals_red_to_yellow_to_green<-colorRampPalette(c("red", "yellow", "green"), space="Lab")(length_val) color_vals_green_to_yellow_to_red<-colorRampPalette(c("green", "yellow", "red"), space="Lab")(length_val) plot(1,1, col = 0, xlim = c(min(x_distance_val), max(x_distance_val)), ylim = c(min(y_distance_val), max(y_distance_val)), xlab = "Room X Position (FT)", ylab = "Room Y Position (FT)", main = "Room Temp vs Position") grid() # filled.contour(ak.fan, col = color_vals_red_to_yellow_to_green) # filled.contour(ak.fan, col = color_vals_green_to_yellow_to_red) # image(ak.fan, col = color_vals_red_to_yellow_to_green, add = TRUE) image(ak.fan, col = color_vals_green_to_yellow_to_red, add = TRUE) ______________________________________________ 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.
