R，按列0合并数据帧

Question

I've got 2 data frames containing timeseries(the time is not coded but there is time variable in column 0).The time variable in column zero doesn't allow to me to merge data frames. The data looks like this: TVC1 AND TVC2 (these are only 2 data frames out of 20)

How can I create time variable or define column zero as time variable to merge the 20 data frames? Thanks,

Answer 1

there is a simple way to convert row names into the 1st column of your data using data.table

library(data.table)
setDT(df, keep.rownames = TRUE)[]

Answer 2

我们可以将数据集放在list ，然后与Reduce merge

Reduce(function(...) merge(..., by = "row.names"), mget(paste0("TVC", 1:20)))
