我对R包学者有疑问
什么有效:
get_citation_history(SSalzberg)
什么不:
get_article_cite_history(SSalzberg, "any article")
代码:
article <- "Ultrafast and memory-efficient alignment of short DNA sequences to the human genome"
SSalzberg <- "sUVeH-4AAAAJ" (Google Scholar ID)
get_article_cite_history(SSalzberg, article)
错误信息:
Error in min(years):max(years) : result would be too long a vector
In addition: Warning messages:
1: In min(years) : no non-missing arguments to min; returning Inf
2: In max(years) : no non-missing arguments to max; returning -Inf
我不理解该函数上下文中的错误消息,我尝试了另一篇文章与另一位作者没有成功.我不知道我在这里失踪了什么....谢谢
