[R] Nested functions.
Hi All, I have two variables X, Y. The question is "if the value of X is equal to one, then the values in Y have to be reversed other wise it should not perfom any action. I think this should be done using lapply function? Example Y values : 1 2 3 NA X Y (ORIGINAL) Y (REVERSED) 1 NA 1 0 --- 1 2 3 1 1 4 1 3 2 ... Can anyone provide solution to this?

[R] Weighting Data
Hi All, Weighting is the procedure to correct the distributions in the sample data to approximate those of the population from which it is drawn. This is partly a matter of expansion and partly a matter of correction or adjustment for both non response and non coverage. It serves the purpose of providing data that look like the population rather than like the sample. The Questions is: Can anyone help me with an small example how to weight data in a survey on Gender,Age ( considering two variable) at a time. (in R) Gender 2 2 1 2 2 Age 61 32 35 26 25 Thanks and Regards, Pratap [[alternative HTML version deleted]] __ R-help@stat.math.ethz.ch 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.
