I am new and self taught in R, so please bear with me. I want to create two scatter plots side by side. The data set includes measurements from two different countries with 7 treatments over a timeline (x-axis).
Problem 1 I want to have each plot to include the data from one of the countries with 7 regression lines of the treatments, but I do no know how to divide the data between them. This is how I created one plot with all the data. > plot(YEAR,YIELD,col="red",xlab="Year",ylab="Yield",xlim=c(1,4),ylim=c(1,150)) Problem 2 The models I've found to describe the regression lines of the treatments seems to be different than the default ablines that R creates. I have the values of the exact values of intercepts and slopes, but does not know how to add them to the graph. This is what I got so far. > abline(lm(YIELD[TREATMENT=="A"]~YEAR[TREATMENT=="A"]),lty=2,col="1") I hope this is enough to give me some pointers, otherwise I will try to elaborate. Thank you for your help. -- View this message in context: http://r.789695.n4.nabble.com/Side-by-side-scatter-plots-with-specified-regression-lines-tp3592473p3592473.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
