Hello R Community, I have the following design question. I have a data set that looks like this (shortened for the sake of example).
Gender Age M 70 F 65 M 70 Each row represents a person with an age/gender combination. We could put this data into a data frame. Now, I would like to do some actuarial analysis on this data set. To do so, I need to create and store a mortality curve for each person in the table (a mortality curve is a matrix with 2 columns: date and survival probability). I can write a function that returns a mortality curve given gender and age. The question is the following: In what data format should I store all these mortality curve objects? Should I add a column to the data frame and each entry in that column is a matrix (a mortality curve)? This way, the mortality curve would be stored next to age/gender data in the data frame. However, I read in several places that putting vectors/matrices as elements of a data frame is a bad idea. I do not know why. What is a good design choice in this instance please? How should I store the mortality curves? Thank you for your help. ______________________________________________ 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.
