Hello All, I am a newcomer to R. Currently, I am trying to write an interactive code in R to let it read the equation which I write and execute the equation in a curve function.
For example: I want to plot curve by using: curve (equation, -2,2, n=1000) what I want is that the R code ask me what equation I want to use (which I know how to write this code): then, I type for example 3*x. then 3*x will be assigned to the 'equation' (I don't know how to do this step) then curve function will work to plot. but I dont' know how I can let the equation to be read in and assigned to equation. I know how to do this kind of thing for numerical values but not for logical equations. Anyone can help out? thanks a lot! czqiu -- View this message in context: http://www.nabble.com/how-to-let-R-read-different-equations-I-write-and-execute-it--tp14243817p14243817.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.
