I have two types of survival data for Drosophila cohort. For example:
uncensored
age <- c (0, 2, 4, 6, 8, 10) alive1 <- c(10, 9, 6, 3, 1, 0) alive 2 <- c(10, 9, 4, 1, 1, 0)
and censored
age <- c(0, 2, 4, 6, 8, 10) alive1 <- c(10, 8, 3, 1, 1, 0) escaped1 <- c(0, 1, 1, 0, 0, 0) alive2 <- c(10, 7, 2, 1, 1, 0) escaped2 <- c(0, 1, 2, 0, 0, 0)
1) What statistical tests is the most apropriate for the correct comparison of uncensored data (alive1 and 2) and censored ones? 2) What package and function I can use in R for the above mentioned comparison? 3) Should I rearrange the data in the example tables for the correct calculations using R functions? With regard, Dmitry. ______________________________________________ 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.
