Hi everyone, I would like to have a function to compute some values in a dataset. First, I have to define a value for the lx variable in row 1 (e.g., 100,000), npx is a given proportion. lx of row 2 is equal to lx of row 1 times npx of row 1. I can do this row by row...
data[1,"lx"] <- 100000 data[2,"lx"] <- data[1,"lx"]*data[1,"npx"] data[3,"lx"] <- data[2,"lx"]*data[2,"npx"] data[4,"lx"] <- data[3,"lx"]*data[3,"npx"] ... data[19,"lx"] <- data[18,"lx"]*data[18,"npx"] Any ideas about how to define this in a function or in a more systematic way? Thank you in advance. -- Sebastián Daza ______________________________________________ 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.
