Dear R users I want to produce scatter plots from the following data set, using R 2.5.0
summary(comps) OBS TM5_STAND Min. : 0.250 Min. : 4.223 1st Qu.: 2.440 1st Qu.: 5.539 Median : 3.936 Median : 6.449 Mean : 4.475 Mean : 6.748 3rd Qu.: 5.790 3rd Qu.: 7.637 Max. : 13.283 Max. :15.452 A simple scatter plot, where I added a linear regression. Here is the code: plot(comps$OBS,comps$TM5_STAND,xlab="observation",ylab="222-Rn model",main="TM5_STAND") abline(lm(comps$TM5_STAND ~ comps$OBS,data=comps)) But as i have to do this for a lot of datasets, I want to compare the R-square and therefore would like to add the R-Square to the plot automatically. I have checked faq and a lot of r-sig-geo messages but haven't found a solution, for this I think trivial problem. Does someone knows a code for this?
