[BioC] Problem installing \'survival\' package/ Fix request + other options?

[Ranjani R [guest]]

Hi,
I have to generate Kaplan-Meier curves and do some survival analysis. From what I understand the 'Survival' package in R is the best bet (please give me other options if you think otherwise).
I've seldom had trouble installing any packages in R - but this one is having me puzzled. I do not have any 'older' versions of the package installed:

install.packages("survival")

Error in library(survival) : there is no package called ‘survival’

What am I doing incorrectly?
