[R] how to make stacked plot?

2010-03-28 Thread sdzhangping
Dear friends: I'm interested to make a stacked plot of cumulative incidence. that's, the cuminc model is fitted [fit=cuminc(time, relapse)] and cumulative incidence is in place. I'd like to stack the cuminc plots(line 1: relapse of luekemia and line 2: treatment related mortality, for

Dear friends: I’m very interested in the analysis of survival data of leukemic patients, which involves competing risks and time-dependent covariates (infections or relapse of leukemia after BMT). In my present work, I’d like to estimate the risk of chemotherapy, BMT or gvhd on the onset and

Dear friends: I have just read an article entitled Monitoring of nosocomial invasive aspergillosis and early evidence of an outbreak using cumulative sum tests (CUSUM), which is published in Clinical Microbiology and Infection. We have great need to estimate the fluctuation of incidence of

Dear R users: In my recent works, I compared the cumulative incidences among three different treatment groups. The cuminc function (cmprsk package ) yielded a graph (refer to figure 1) and a p value (p = 0.0007). I don’t know how to interpret the meaning of the p value ( one p value and

Dear R users: Analysis of the impact of a time-dependent covariate (GVHD or use of steroid after bone marrow transplantation) on two competing endpoints (invasive fungal infection and death) is frequently encountered in the setting of BMT data. Coxph package can be used as the following:
