Concatenate vectors after converting to character.
paste(..., sep = " ", collapse = NULL)
... |
one or more R objects, to be converted to character vectors. |
sep |
a character string to separate the terms. Not
|
collapse |
an optional character string to separate the results. Not
|
paste converts its arguments (via
as.character) to character strings, and concatenates
them (separating them by the string given by sep). If the
arguments are vectors, they are concatenated term-by-term to give a
character vector result. Vector arguments are recycled as needed,
with zero-length arguments being recycled to "".
Note that paste() coerces NA_character_, the
character missing value, to "NA" which may seem
undesirable, e.g., when pasting two character vectors, or very
desirable, e.g. in paste("the value of p is ", p).
If a value is specified for collapse, the values in the result
are then concatenated into a single string, with the elements being
separated by the value of collapse.
A character vector of the concatenated values. This will be of length
zero if all the objects are, unless collapse is non-NULL in
which case it is a single empty string.
If any input into an element of the result is in UTF-8, that element will be in UTF-8, otherwise in the current encoding in which case the encoding of an element of the element is declared if the current locale is either Latin-1 or UTF-8, at least one of the corresponding inputs (including separators) had a declared encoding and all inputs were either ASCII or declared.

String manipulation with
as.character, substr, nchar,
strsplit; further, cat which concatenates and
writes to a file, and sprintf for C like string
construction.
