[R] consolidate three function into one

[Ding, Yuan Chun]

HI R users,

I construct dendrogram tree and cut the tree into different clusters, then generate survival curves by the following three functions. All variables are included in an inputfile. 

Can you help me to consolidate the following three function into one functions?  I thought about using if  else function, but not sure how to do it.

Thank you,

Ding

# function to generate RFS
RFS2cluster <- function( inputfile ) {
  cluster2<- survfit(Surv(RFS_days, OV_Had_a_Recurrence_CODE) ~ clusters,
                               data = inputfile)
  
  ggsurvplot(cluster2, data = inputfile, risk.table = F,
             palette = c("red", "black"),
             ylim=c(0,1),
             ggtheme = theme_bw(),
             xlab="Relapse Free Suvival (Days)",

hello,
Can you please give me a hand with this problem,well i can't install these
packages:
- stats
- methods
- stats4

when i tried the following command :  *library(help = "stats") * , it gave me this output (*see picture*), so i contacted the Maintainer of the package at (*R-core at r-project.org <R-core at r-project.org>*) but he said that i write to the wrong place.

(i want to install those packages in order to use the "DVstats" package)

(i have the latest version of R (3.4.3 ) and Rstudio(1.2.240) )

thank you
Regards
