Hi all, I have a puzzling problem related to nchar. In R 3.2.1, the internal nchar gained an extra argument (see https://stat.ethz.ch/pipermail/r-announce/2015/000586.html)
I've been testing code using the package copula, and at home I'm still running R 3.2.0 (I know, I know...). When trying the following code, I got an error: > library(copula) > fgmCopula(0.8) Error in substr(sc[i], 2, nchar(sc[i]) - 1) : 4 arguments passed to .Internal(nchar) which requires 3 So I do the obvious and try to debug using debug(): > debugonce(fgmCopula) > fgmCopula(0.8) And when I try that, I can step through the complete function without any error. I know that the obvious solution is to update to R 3.2.2, but : - I have absolutely no clue how a function can give an error when used normally, but not return any error when stepping through it using debug. - The copula package built for R 3.2.2 isn't compatible any longer with R versions older than R 3.2.1, like the one used in our PC classes. Other packages might share the same problem. Can somebody shed some light on what exactly is going on here? I don't want to bug the authors of the copula package if I'm not sure of the origin of this problem.
