Hello,

I need to print a screen message after a test.

>list<-c("10","1","100","10")
>ifelse(all(list %in% c(1,10,100)==TRUE),cat("YES\n"),cat("NO\n"))
YES
Error in ifelse(all(l %in% c(1, 10, 100) == TRUE), cat("YES\n"), cat("NO\n")) : 
  replacement has length zero


I have the correct answer, YES, but with an Error.

Why?

TY for any help
