Have you tried the packages 'survival' and 'eha' yet? You can use the survreg() function in the former to compare between different models.
Have a look at this tutorial: http://www.openintro.org/stat/surv.php (a copy can also be found here: http://anson.ucdavis.edu/~hiwang/teaching/10fall/R_tutorial%201.pdf)
Here's the task view to learn what's available in R to run survival analysis: http://cran.r-project.org/web/views/Survival.html
Hope this helps.

Subject: [R] Adjusting published survival functions
I would like to know how to adjust survival functions in R and after reading lots of posts I don't have it clear. I downloaded the fitdistrplus package but it seems me like it only fits univariately the functions.
Being specific , having a survival curve which corresponds to a set of data such as:
i'm searching the parameters that fit with the curve with loglogistic, lognormal and weibull, and then, comparing the AICs of the adjustments, to select the best fit curve.
Could you please help me?
Thank you in advance,
