I am a new user of R and I use a simple code to draw a scatterplot in openair package.
scatterPlot(mydata, x = "e_flw", y = "m_flw", linear = TRUE)
For surface pressure datasets (values changes btw 800-1000 kPa) the equation of line and R2 value is not shown on the graph. I don't have such a problem on the other datasets like precipitation or temperature.
Do you have any idea how can I get the R2 value on graph?
