Problems with entries_to_df and entries_to_affil_list #27

Closed longhotuan closed 4 years ago

longhotuan commented 5 years ago

Many thanks for a great package!

However, I have encountered an issue when using entries_to_df and entries_to_affil_list

water <- scopus_search(query = 'TITLE-ABS-KEY ( water AND ( "academy" OR "access" OR "access to sanitation" )) AND AFFILCOUNTRY ( belgium ) AND PUBYEAR > 2008') water_df <- entries_to_df(water$entries) water_aff <- entries_to_affil_list(water$entries) The error happens with entries_to_df is | | 0%Error in$<-.data.frame(*tmp*, "n_auth", value = -Inf) : replacement has 1 row, data has 0 In addition: Warning message: In max(as.numeric(res$seq)) : no non-missing arguments to max; returning -Inf

While with entries_to_affil_list, it returns a list containing only null elements

Please help me with this! Thank you very much!

Use gen_entries_to_df, not entries_to_df:

water <- scopus_search(query = 'TITLE-ABS-KEY ( water AND ( "academy" OR "access" OR "access to sanitation" )) AND AFFILCOUNTRY ( belgium ) AND PUBYEAR > 2008')

water_df <- gen_entries_to_df(water$entries) 
head(water_df$affiliation)
