Print binary output in knitr

Question

Just showing an example to represent my seemingly simple problem.

i generate a variable with random TRUE/FALSE.

<<>>=
data <- sample(c(TRUE, FALSE), size = 1, replace = TRUE)
@

Somewhere in the TeX (knitr), i need to print whether its TRUE or FALSE.

\Sexpr{!is.na(data)}

but my text output is blank. I am not sure whats the problem?

Answer 1

Do the following:

\documentclass[10pt,letterpaper]{article}

\begin{document}
<<>>=
data <- sample(c(TRUE, FALSE), size = 1, replace = TRUE)
@

\Sexpr{data}
\end{document}
