编辑：根据Parfait的建议，我通过指定ISO-8859-1编码而不是UTF_8找到了成功。
我正在阅读IEEE文章元数据＆amp;摘要。
我正在遍历多个结果页面。我的代码一直运行良好，但是这一点导致了以下错误：
require(XML)
link <- "http://ieeexplore.ieee.org/gateway/ipsSearch.jsp?py=1934&hc=100&rs=1"
doc <- xmlParse(link, encoding = "UTF_8", options = NOCDATA)
错误：
input conversion failed due to input error, bytes 0x20 0x62 0x65 0x66

Premature end of data in tag title line 3081

我遇到了与此数据集相同的错误，但是通过一次读取较小的数据集（现在hc = 100而不是hc = 1000）成功解析了它。
此处列出了网关查询参数： http://ieeexplore.ieee.org/gateway/
为什么会出现这种错误以及我可以做些什么来解决它？
