vecTxtQ
, vecTxtB
, and vecTxtM
and are convenience functions
with default quotes that can be useful when working in R Markdown
documents.
vecTxt(
vector,
delimiter = ", ",
useQuote = "",
firstDelimiter = NULL,
lastDelimiter = " & ",
firstElements = 0,
lastElements = 1,
lastHasPrecedence = TRUE
)
vecTxtQ(vector, useQuote = "'", ...)
vecTxtB(vector, useQuote = "`", ...)
vecTxtM(vector, useQuote = "$", ...)
The vector to process.
The delimiters
to use for respectively the middle, first
firstElements
, and last lastElements
elements.
This character string is pre- and appended to all elements;
so use this to quote all elements (useQuote="'"
), doublequote all
elements (useQuote='"'
), or anything else (e.g. useQuote='|'
).
The only difference between vecTxt
and vecTxtQ
is that the
latter by default quotes the elements.
The number of elements for which to use the first respective last delimiters
If the vector is very short, it's possible that the
sum of firstElements and lastElements is larger than the vector length. In
that case, downwardly adjust the number of elements to separate with the
first delimiter (TRUE
) or the number of elements to separate with the
last delimiter (FALSE
)?
Any addition arguments to vecTxtQ
are passed on to
vecTxt
.
A character vector of length 1.
