How to print a blank line from within a function?
25,311
You should cat a newline character twice. By writing cat(x); cat('\n'); cat(x)
, with x=="test"
you if fact print("test\ntest")
-- there's only one newline here.
A possible solution:
prnt.test <- function(x){
cat(x, sep="\n\n")
}
prnt.test(c("test1", "test2", "test3"))
## test1
##
## test2
##
## test3

I want to write a function to print some output with blank lines in between. Using examples such as
surv:::print.coxph
, I saw that this can be done usingcat("\n")
. however, when I try that in a function, only the firstcat("\n")
gives a blank line as output, while the second does not. Here's an example:prnt.test <- function(x){ cat("\n") cat(x) cat("\n") cat(x) } prnt.test(x="test") # Output: test test
Any ideas on how to print a blank line within the two
test

Many thanks!
