help
Dear R Help group I need to run a command line script from within R session. I am not clear how i can acheive this. I tried shell and system function, but i am missing something critical.can someone provide help? My intention is to create a pdf file of a plot in R and then attach existing files from my system as attachment into the newly created pdf file. Any help would be greatly appreciated..

parametric proportional hazard regression
...all, I am trying to find a suitable R-function for parametric proportional hazard regressions. The package survival contains the coxph() function which performs a Cox regression which leaves the base hazard unspecified, i.e. it is a semi-parametric method. The package Design contains the function pphsm() which is good for parametric proportional hazard regressions when the underlying base distribution is "weibull" or "exponential". But what if I need a parametric proportional hazard model with the other "usual" distributions like '"gaussian"', '...

survival parametric question
Hi to all, I am working on design package using survival function. First using PSM and adopting a weibull specification for the baseline hazard , I have got the following results(since weibull has both PH and AFT propreties ,in addition I have used the PPHSm command): Value Std. Error z p (Intercept) 1.768 1.0007 1.77 7.73e-02 SIZE -0.707 0.0895 -7.90 2.80e-15 REtoTA -0.896 0.4208 -2.13 3.33e-02 D1toEQ 0.281 0.0330 8.51 1.81e-17 EBTtoTA -6.706 1.0807 -6.21 5.46e-10 SALtoTA -3.94...

Weibull survival regression
...e (x) ??? I cannot control the axes with labeling and any other covariate gets the same plot. I have tried using covariates in the Design and Survival packages, but they always return the same error msgs. I realise that the former 2 are AFT survival models, but even when I convert the object with pphsm() in the Design package, I get the same errors. Please can anyone enlighten me as to what I seem to be doing / understanding wrongly?

(no subject)
Hello I would like to compare the results obtained with a classical non parametric proportionnal hazard model with a parametric proportionnal hazard model using a Weibull. How can we obtain the equivalence of the parameters using coxph(non parametric model) and survreg(parametric model) ? Thanks Virginie
