A correlation coefficient close to 0 suggests little, if any, correlation.

Is there a way to combine multiple plots in R?

Combining Plots . R makes it easy to combine multiple plots into one overall graph, using either the par( ) or layout( ) function. With the par( ) function, you can include the option mfrow=c(nrows, ncols) to create a matrix of nrows x ncols plots that are filled in by row. mfcol=c(nrows, ncols) fills in the matrix by columns.
