我有一个df如下

structure(list(ProductAccountNumber = c(17397841L, 17397841L, 
                                        17397841L, 17397841L, 17397841L, 17397841L, 17397841L, 17397841L,

                                ), class = "data.frame")

我想转换它，使所有的日期从OriginalDate/RefreshFICODateX成为列名和列的值来自OriginalFICO/RefreshFICOX。

我可以一次用一组原始/刷新相当容易地做到这一点，但有10个，必须有一个更简单的方法。是否可以告诉pivot_wider之类的东西在某种意义上“配对”列。

类似@Onyambu的方法：

#make uniform column names
names(fico) <- c("ProductAccountNumber", "Date_1", "FICO_1",  "Date_2", "FICO_2", "Date_3", "FICO_3")
#get all columns in a similar data format
fico$Date_1 <- as.Date(fico$Date_1, "%Y-%m-%d" )

#Pivot longer then wider
long <- pivot_longer(fico, -ProductAccountNumber, names_sep = "_", names_to = c(".value", "count"), values_to = "value")
pivot_wider(long, id_cols = "ProductAccountNumber", names_from = "Date", values_from = "FICO", values_fn = mean )

  ProductAccountNumber `2009-04-14` `2012-10-15` `2012-07-05` `2013-07-15` `2013-04-12` `2015-04-06` `2015-08-14` `2015-10-09` `2016-05-11` `2016-07-19`
