knit_filter {knitr} | R Documentation |
When performing spell checking on source documents, we may need to skip R
code chunks and inline R expressions, because many R functions and symbols
are likely to be identified as typos. This function is designed for the
filter
argument of aspell()
to filter out code chunks
and inline expressions.
knit_filter(ifile, encoding = "unknown")
ifile |
the filename of the source document |
encoding |
the file encoding |
A chracter vector of the file content, excluding code chunks and inline expressions.
