Dear all, I would like to know if it’s possible to create an index for a variable/vector that specifies the value in the n position before the actual value.
For example, if X <- c(letters[1:10]), x[10] is “j”. I would like to create an index exp3 (the third position before) such as if z <- x[exp3], then z[10] = “g”. In Stata that index is x[-3], but not in R. I have to input it in a very complex function to be minimised with the mle command, so I can’t solve this problem with a loop. Can you help me? ______________________________________________ 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.
