Retrieve a pattern or set of patterns from the COLOURlovers API.
clpatterns(set = NULL, ..., fmt = "xml")clpattern(id, fmt = "xml")
Optionally, a subset of COLOURlovers patterns. Allowed values are “new”, “top”, and “random”.
A named list of parameters passed to the API request. Allowed
parameters are lover
, hueOption
, hex
, hex_logic
,
keywords
, keywordExact
, orderCol
, sortBy
,
numResults
, and resultOffset
. Specifying orderCol
overrules any argument to set
. See details.
A format for the API response, one of “xml” (the default) or “json”. This has essentially no effect on function behavior.
The COLOURlovers id (an integer) for a specific pattern.
A list of class “clpattern”. This should be the same
regardless of the value of fmt
.
Retrieve details about a pattern or set of patterns.
Specifying named arguments to ...
allows the user to request a
specific response, as follows:
lover
: A character string containing a COLOURlovers username.
hueOption
: A character vector containing one or more named hues to
search by. Allowed values are: “red”, “orange”,
“yellow”, “green”, “aqua”, “blue”,
“violet”, “fuchsia”. Any other values other than these named
colors will be ignored.
hex
: A character vector containing up to five colors specified as
hexidecimal representation (with or without a leading hash symbol). Excess
colors will be ignored.
hex_logic
: A character value containing either “AND” (the
default) or “OR”, for whether the values in hex
should be
searched for with a boolean AND versus OR logic. Specifying “AND”
will only return palettes with all requested colors.
keywords
: A character string containing one or more keywords to
search by.
keywordExact
: A boolean indicating search on keywords should be
exact (TRUE
) or not (FALSE
, the API default).
orderCol
: A character string containing a sort criterion. One of
“dateCreated”, “score”, “name”, “numVotes”,
“numViews”.
sortBy
: A character string containing either “ASC” (for
ascending by the orderCol
criterion, the default) or “DSC”
(for descending).
numResults
: A numeric value indicating the number of results to
return, with a maximum of 100. Default is 20.
resultOffset
: A numeric value indicating the page of results to
return, with page size specified in the numResults
argument.
