Let's say I have the following vector:
output <- c("foo\n", "bar\n")
If I want to display this via cat
, I get a weird indentation:
> cat(output)
foo
bar
Why is there a space before "bar
"? I can get around it with paste
:
> cat(paste(output, collapse = ""))
foo
bar
but I don't understand why cat
is behaving in this fashion in the first place? Is this a bug, or am I missing something about how cat
behaves?
CodePudding user response:
cat
has a sep
argument.
From ?cat
:
sep
: a character vector of strings to append after each element.
sep
defaults to " "
.
Hence:
output = c("foo\n", "bar\n")
cat(output, sep = "")
foo
bar
