[R] survival curve to compare two groups

[Linda Lei]

Hi All,

 

I want to get the OS and EFS curve to compare two groups by log-rank
test. I can draw the two curves by "survfit" but I couldn't find
"log-rank" test in the choices of argument. I also looked at the
"survdiff" which does have "log-rank" test, but it seems like no plots
can be drawn from it.

Could you please help me with it?

 

The attached are the data and code.

 

Thank you!
