我正在尝试使用 R 包RecordLinkage将采购订单列表中的项目与主目录中的条目进行匹配。下面是 R 代码和使用两个虚拟数据集（DOrders 和 DCatalogue）的可重现示例：
DOrders <- structure(list(Product = structure(c(1L, 2L, 7L, 3L, 4L, 5L,
6L), .Label = c("31471 - SOFTSILK 2.0 SCREW 7mm x 20mm", "Copier paper white A4 80gsm",
"High resilience memory foam standard mattress", "Liston forceps bone cutting 152mm",
"Micro reciprocating blade 25.4mm x 8.0mm x 0.38mm", "Micro reciprocating blade 39.5 x 7.0 x 0.38",
"microaire dual tooth 18 x 90 x 0.89"), class = "factor"), Supplier = structure(c(5L,
6L, 2L, 1L, 4L, …
