cSurv is a character representation of survival::surv ###

cSurv serves as a more reliable way to use Surv objects as data.frame columns. A data.frame is supposed to be able to hold Surv columns. There are multiple special cases written into base for this. It seems the implementation is incomplete as subsetting the DF breaks the Surv object. cSurv cannot do anything but get subset and become a Surv again. In the FacileVerse we hold Surv objects as cSurv, which allows us to survive a round-trip through an EAV sample metadata table. Survival analyses can convert cSurv to Surv as needed. It is assumed that all Surv censoring is right-censored.

Examples

library(survival)
x = Surv(c(14,12,3), event = c(1,0,1))
y = as(x,"cSurv")
z = as(y, "Surv")
x2 = as.character(x)
z2 = as(x2, "Surv")
a = as(x, "cSurv")
b = as(a, "character")
c = as(b, "cSurv")
d = as(c, "Surv")
