Question

我试图通过从不同的数据框中提供行名和列名来更改数据框中一个单元格的值。

我能够将值存储在变量中，但不能将变量或任何其他值分配给单元格。

a <- DF[DF1$Date ,names(DF2[2])] # works, stores value in a 

DF[DF1$Date ,names(DF2[2])] <- 2 # does not works. Gives error 
DF[DF1$Date ,names(DF2[1])] <-  a # does not work either. Same error

Summary.factor中的错误（20L，na.rm = FALSE）： 'max'对因素没有意义另外：警告信息：在Ops.factor（i，0L）中：'＆gt; ='对因子无意义

dput（头（DF2））

structure(list(B_Dryer.egaugekW = 1.9727155555,
 D_GroundSourceHeatPumpkW =   0. 603251389, 
 F_BasementkW = 0.30035222225), .Names = c("B_Dryer.egaugekW", 
 "D_GroundSourceHeatPumpkW", "F_BasementkW"), row.names = 1L, 
  class =   data.frame")

dput（head（DF1））#DF的子集

dput（head（DF））＃一年的数据。提供第一行
