cat is useful for producing output in user-defined functions.
It converts its arguments to character vectors, concatenates
them to a single character vector, appends the given
string(s) to each element and then outputs them.
No linefeeds are output unless explicitly requested by "\n"
or if generated by filling (if argument
file is a connection and open for writing it is written from
its current position. If it is not open, it is opened for the
duration of the call in
"wt" mode and then closed again.
Currently only atomic vectors and names are handled,
NULL and other zero-length objects (which produce
no output). Character strings are output ‘as is’ (unlike
print.default which escapes non-printable characters and
backslash — use
encodeString if you want to output
encoded strings using
cat). Other types of R object should be
converted (e.g., by
before being passed to
cat. That includes factors, which are
output as integer vectors.
cat converts numeric/complex elements in the same way as
which is used by the S equivalent), so
"scipen" are relevant. However, it uses
the minimum field width necessary for each element, rather than the
same field width for all elements.
If any element of
sep contains a newline character, it is
treated as a vector of terminators rather than separators, an element
being output after every vector element and a newline after the
last. Entries are recycled as needed.
