Question

我有一个数据集，其中的列名称之一是“名称”，其中包含产品名称，包括产品的数量（尺寸），如下所示。

Alkabeer Paratha Plain 400 GM
Almarai Fresh Laban Baladi 2 L
Americana Breaded Chicken Burger 1 KG 
Dac Glass Cleaner 4 L
Duru Body Soap Fruity 125 GM - 4 Pcs
Lux Liquid Handwash Soft Touch 250 ML
Lux Liquid Handwash Magical Beauty 250 ML
Lusine Sliced Bread Multi Grain 600 GM
Orinex Containers Bowl 25 Oz - 4 Pcs
Betty Crocker Frosting Vanilla 400 GM
Freshly Microwave Popcorn 3.5 Oz
Gandour Potato Chips 145 Gm  
Galaxy Chocolate Milk 40 GM
Nahool Jumbo Roll Strawberry 75 GM - 6 Pcs
Nestle Sweetened Condensed Milk 397 GM 
Puck Cheese Triangle Value Pack 120 GM - 5 Pcs
Betty Crocker Super Moist Cake Mix Choco Fudge 500 GM

某些产品包装在板条箱中，例如“ Duru香皂果味125 GM-4件”

我想提取箱子的数量和大小（如果不是箱子则为0）。

数量由GM，KG，ML，L，Oz定义，箱子的尺寸由Pcs确定

编辑：

我想添加更多示例，这些示例使Onyambu提到的过程变得复杂。

在Base R中执行此操作：

read.table(sep="-",text=gsub(".*?(\\d+.*)","\\1",dat$V1),fill=T,h=F,
      col.names = c("Quantity","Crate_Size"),na.strings = "",strip.white = T)
