问题描述
我给了我这个组织不好的数据表,其中有数百列(子集在下面给出)
列名以点分隔,其中第一个字段包含有关对象类型(例如Item123,object_AB等)的信息,而没有任何命名约定。这些列也没有特定的顺序。 其他列共享对象字段的类型,并且还具有该对象的某些属性的名称(例如颜色,制造商等)。
Item123.type.value Item123.mass.value Item123.color.value object_AB.type.value object_AB.mass.value object_AB.color.value
Desk 11.2 blue Chair 2.3 orange
Desk 14.2 red Sofa 22 grey
Armchair 23.3 black Monitor 2.2 white
编辑:添加dput()结构:
structure(list(Item123.type.value = structure(c(2L,2L,1L),levels = c("Armchair","Desk"),class = "factor"),Item123.mass.value = structure(1:3,levels = c("11.2","14.2","23.3"),Item123.color.value = structure(c(2L,3L,levels = c("black","blue","red"),object_AB.type.value = structure(c(1L,2L),levels = c("Chair","Monitor","Sofa"),object_AB.mass.value = structure(c(2L,levels = c("2.2","2.3","22"),object_AB.color.value = structure(c(2L,1L,3L),levels = c("grey","orange","white"),class = "factor")),row.names = c(NA_integer_,-3L),class = "data.frame")
我需要将表转换成这样(行的顺序无关紧要):
type name mass color
Item123 Desk 11.2 blue
Item123 Desk 14.2 red
object_AB Chair 2.3 orange
object_AB Sofa 22 grey
Item123 Armchair 23.3 black
object_AB Monitor 2.2 white
我将非常感谢我能获得的任何帮助!
