我有两个数据帧，我给出了它们的结构。
dataset1 <- rbind.pages(lapply(filesjsonrformat,fromJSON))
dataset2 <- fromJSON(sprintf("[%s]",
paste(readLines("filesrjsonformat2.jsonr"), collapse=",")))
str(dataset1)
data.frame': 772517 obs. of 19 variables:
$ status : chr "OPEN" "OPEN" "OPEN" "OPEN" ...
$ datejlc : POSIXct, format: "2015-09-15 22:13:20" "2015-10-09
17:14:40" "2015-09-18 12:06:23" "2015-09-10 00:20:37" ...
$ hour : int 23 18 13 1 1 19 16 12 15 9 ...
$ date : chr "2015-09-15" "2015-10-09" "2015-09-18" "2015-
09-10" ...
$ days : chr "mardi" "vendredi" "vendredi" "jeudi" ...
str(dataset2)
'data.frame': 4416 obs. of 2 variables:
$ status: chr "ok" "ok" "ok" "ok" ...
$ data :'data.frame': 4416 obs. of 32 variables:
.. ..$ year : chr "2015" "2015" "2015" "2015" ...
.. ..$ tzname: chr "Europe/Paris" "Europe/Paris" "Europe/Paris"
"Europe/Paris" ...
..$ utcdate :'data.frame': 4416 obs. of 7 variables:
.. ..$ mday : chr "31" "31" "31" "31" ...
.. ..$ hour : chr "00" "00" "01" "01" ...
.. ..$ min : chr "00" "30" "00" "30" ...
.. ..$ mon : chr "08" "08" "08" "08" ...
.. ..$ pretty: chr "12:00 AM GMT on August 31, 2015" "12:30 AM GMT on
August 31, 2015" "1:00 AM GMT on August 31, 2015" "1:30 AM GMT on August
31, 2015" ...
.. ..$ year : chr "2015" "2015" "2015" "2015" ...
.. ..$ tzname: chr "UTC" "UTC" "UTC" "UTC" ...
即使它们的尺寸不同，我怎样才能合并它们按日期加入？我尝试在两种情况下都使用UTC作为时区
