Contour plot in r. This function produces a contour plot with the areas between the contours filled in solid color Cleveland calls this a level plot. Libraryggplot2 setseed1 df. You just need to pass your data frame and indicate the x and y variable inside aes.
It is is intended for programmatic use and the programmer is responsible for. R - ggplot2 contour plot. This page shows how to use R to draw a table or matrix of numerical values as a contour plot with an overlayed grid like the image below and using level-plots as an alternative.
A key showing how the colors map to z values is shown to the right of the plot. We then develop visualizations using ggplot2 to gain more control over the graphical output. Plot tunedsvm transformx log2 transformy log2 log 2 scale for x and y transformz function x 1 - x convert error rate to accuracy rate swapxy TRUE put gamma on y axis colorpalette terraincolors define color palette for contours xlab expression log cost ylab expression log gamma main Accuracy Rate of SVM.
The data consists of z values on a xy grid similar to the 3D surface plot. Now I want to smooth these figures and show them as contour plots. One idea would be to start with a two-dimensional histogram.
The ContourFunctions R package provides functions that make it easier to make contour plots. The library plot3D has a function called contour2D in plot3d library that can produce a contour plot. I am trying to replicate the code from Andrew Ngs Machine Learning course on Coursera in R as the course is in Octave.
This function produces a contour plot with the areas between the contours filled in solid color Cleveland calls this a level plot. Filledcontouris a bare bones interface to add just the contour plot to an already-set-up plot region. This plot is Figure 2 from Lu et al 2003 and shows their residue based Protein-Protein Interaction Potential between each of the twenty amino acids.
