| httr_options {httr} | R Documentation |
This function lists all available options for config().
It provides both the short R name which you use with httr, and the longer
Curl name, which is useful when searching the documentation. curl_doc
opens a link to the libcurl documentation for an option in your browser.
httr_options(matches) curl_docs(x)
matches |
If not missing, this restricts the output so that either the httr or curl option matches this regular expression. |
x |
An option name (either short or full). |
RCurl and httr use slightly different names to libcurl: the initial
CURLOPT_ is removed, all underscores are converted to periods and
the option is given in lower case. Thus "CURLOPT_SSLENGINE_DEFAULT"
becomes "sslengine.default".
A data frame with three columns:
httr |
The short name used in httr |
libcurl |
The full name used by libcurl |
type |
The type of R object that the option accepts |
