我有一个 CSV，它似乎是 Excel 数据透视表的输出，其名称嵌套为重复组的行标签。我想清理数据，以便行标签在单独的列中重复，最好使用 dplyr。
数据如下：
dd <- data.frame(variables = c("Abington", "Number of Sales","YTD Number of Sales","Median Sale Price","YTD Median Sale Price", "Acton", "Number of Sales","YTD Number of Sales","Median Sale Price","YTD Median Sale Price"), Year1 = c(" ", 16, 50,415000,413500," ",23,60,799900,704000), Year2 = c(" ",8,13,583000,575000," ",9,39,995000,800000))
dd
variables Year1 Year2
Abington
Number of Sales 16 8
YTD Number of Sales 50 13
Median Sale Price 415000 583000
YTD Median Sale Price 413500 575000
Acton
Number of Sales 23 9
YTD …
