[R] How can I doing Quality adjusted survival analysis in R?
Thaks Ryusuke, One question, is it possible to have an increased quality adjusted survival during a period of time? I ask that because I saw a paper published in a cientific journal with a adjusted survival curve that increase during a period and dicrease after that.

You can prepare only the so-called Partitioned Survival Analysis, but those are without the quality of life weights. I describe Partitioned analysis in my paper in The American Statistician and give citations to description of the method in a Biometrics paper. There are several variations on quality adjusted survival analysis, that incorporate the quality of life scores- and you would need to program those on your own. The most well known is called "Q-TWIST" analysis originally published in the Journal of Clinical Oncology. 19. Goldhirsch A, Gelber RD, Simes RJ, Glasziou P, Coates AS.
