A merges lines while preserving the line break for HTML/LaTeX

This function helps you to do a table header with multiple lines in both HTML and in LaTeX. In HTML this isn't that tricky, you just use the <br /> command but in LaTeX I often find myself writing vbox/hbox stuff and therefore I've created this simple helper function

txtMergeLines(..., html = 5)

Arguments

...

The lines that you want to be joined

html

If HTML compatible output should be used. If FALSE it outputs LaTeX formatting. Note if you set this to 5 then the HTML5 version of br will be used: <br> otherwise it uses the <br /> that is compatible with the XHTML-formatting.

Value

string with asis_output wrapping if html output is activated

Other text formatters: txtInt(), txtPval(), txtRound()

Examples

txtMergeLines("hello", "world")
#> [1] "hello<br>\n world"
#> attr(,"class")
#> [1] "knit_asis"
#> attr(,"knit_cacheable")
#> [1] NA
txtMergeLines("hello", "world", html=FALSE)
#> [1] "\\vbox{\\hbox{\\strut hello}\\hbox{\\strut world}}"
txtMergeLines("hello", "world", list("A list", "is OK"))
#> [1] "hello<br>\n world<br>\n A list<br>\n is OK<br>\n A list<br>\n is OK"
#> attr(,"class")
#> [1] "knit_asis"
#> attr(,"knit_cacheable")
#> [1] NA
