WebScatter Plot Matrices - R Base Graphs. Previously, we described the essentials of R programming and provided quick start guides for importing data into R. Here, we’ll describe how to produce a matrix of scatter plots. This is useful to visualize correlation of small data sets. The R base function pairs () can be used. WebI tried the solution in here to get the customWorkspace for each different matrix axis build. However, when Jenkins compiles, it does not translate the ${job_name}/${BUILD} correctly. In fact, it just shows 2 folders in the workspace: A folder called ${job_name} Another folder called "project" namespace
