Survival Analysis Using R Example
Formula is the relationship between the predictor variables. Following are the initial steps you need to start the analysis. F(t) is the cumulative distribution function with F(t) Pr. Fit - coxph(Surv(time, status)lwt.
For collaboration and sensitive data, netflix you can run Plotly on your own servers. Regularised and shrinkage methods: The glmnet package provides procedures for fitting the entire lasso or elastic-net regularization path for Cox models. Failure netflix time in mechanical systems. Kaps implements K-adaptive partitioning and recursive partitioning algorithms for censored survival data.

David Diezs Survival Analysis with R - OpenIntro
The temporal process regression model is implemented in the tpr package. A Cox model with piecewise constant hazards can be fitted using the pch package. The etm package estimates and plots transition probabilities for any multistate models. PlsRcox provides partial least squares regression and various techniques for fitting Cox models in high dimensionnal settings. The addhazard package contains tools to fit additive hazards model to random sampling, two-phase sampling and two-phase sampling with auxiliary information. The ltrctrees package provides recursive partition algorithms designed for fitting survival tree with left-truncated and right censored data. The discSurv provides data transformations, estimation utilities, predictive evaluation measures and simulation functions for discrete time survival analysis.
We can conclude that your unbalanced sample is a threat to validity of the Cox method. The SimHaz package permits to simulate data with a dichotomous time-dependent exposure. The x package fits Cox proportional hazards model using the compound covariate method.
Fits latent variable models for censored outcomes via a probit link formulation. The mets package implements various statistical models for multivariate event history data.
The thregI package permits to fit a threshold regression model for interval-censored data based on the first-hitting-time of a boundary by the sample path of a Wiener diffusion process. An alternative algorithm for random forests is implemented in icRSF.

Non-parametric estimates in illness-death models and other three state models can be obtained with package. The package also implements the Fine and Gray model for regressing the subdistribution hazard of a competing risk.
