Comparable behaviour regarding line breaks for `cat()` can be achieved via setting its `sep` argument to `"\n"`:

```{r, eval=FALSE}
multiline_cat <- function(sep = "\n") {
cat("first", sep = sep)
cat("second", sep = sep)
}

multiline_cat(sep = "\n")
#> first
#> second
multiline_cat(sep = "")
#> firstsecond
```
