如何解决如何在R中使用jsonlite读取此JSON文件？

我正在尝试从以下网站读取R中的“ arxiv-metadata-oai-snapshot.json”：https://www.kaggle.com/Cornell-University/arxiv?select=arxiv-metadata-oai-snapshot.json我已经下载了数据并将其重命名为“ arxiv.json”。

借助于R中的“ jsonlite”包，我正在尝试读取“ arxiv.json”，但这是不可能的：

//-- set the new page arguments
$new_page_args = array(
    'post_type'     => 'page',//-- this is of type 'page'
    'post_title'    => 'My Dynamic Page',//-- title of the page              
    'post_status'   => 'publish'            //-- publish the page
);

//-- insert the page
$new_page_id = wp_insert_post( $new_page_args );

if( is_wp_error( $new_page_id ) )
{
    echo 'Unable to create the page!';        
    die;
}

if( defined( 'ELEMENTOR_VERSION' ) )    //-- if FREE version of Elementor plugin is installed
{
    update_post_meta( $new_page_id,'_elementor_version',ELEMENTOR_VERSION );
}

if( defined( 'ELEMENTOR_PRO_VERSION' ) )    //-- if PRO version of Elementor plugin is installed
{
    update_post_meta( $new_page_id,'_elementor_pro_version',ELEMENTOR_PRO_VERSION );
}

update_post_meta( $new_page_id,'_wp_page_template','page-fullwidth.php' );    //-- for using full width template

//-- for Elementor
update_post_meta( $new_page_id,'_elementor_edit_mode','builder' );
update_post_meta( $new_page_id,'_elementor_template_type','wp-page' );

//-- Elementor layout
update_post_meta( $new_page_id,'_elementor_controls_usage','a:3:{s:17:"listings_grid_new";a:3:{s:5:"count";i:1;s:15:"control_percent";i:1;s:8:"controls";a:1:{s:7:"content";a:1:{s:13:"section_query";a:2:{s:7:"loc_ids";i:1;s:7:"tag_ids";i:1;}}}}s:6:"column";a:3:{s:5:"count";i:1;s:15:"control_percent";i:0;s:8:"controls";a:1:{s:6:"layout";a:1:{s:6:"layout";a:1:{s:12:"_inline_size";i:1;}}}}s:7:"section";a:3:{s:5:"count";i:1;s:15:"control_percent";i:0;s:8:"controls";a:0:{}}}' );

$tag_id = '56'; //-- new value
//-- Elementor data ( I have injected the new $tag_id value in the string )
update_post_meta( $new_page_id,'_elementor_data','[{"id":"2e0569b","elType":"section","settings":[],"elements":[{"id":"e2a6dbb","elType":"column","settings":{"_column_size":100,"_inline_size":null},"elements":[{"id":"441552a","elType":"widget","settings":{"tag_ids":"'. $tag_id .'"},"elements":[],"widgetType":"listings_grid_new"}],"isInner":false}],"isInner":false}]' );

我收到以下错误：

library(jsonlite)
arxiv <- fromJSON(file = "C:/Users/caproki/Downloads/arXiv Dataset/arxiv.json")

我该怎么办？预先感谢！
