Вы можете сделать это, используя базу R
df <- unique(data.frame(Timestamp=as.POSIXct(strptime(c('2018-01-08 13:26:53',
'2018-01-08 13:33:33',
'2018-01-08 13:45:12',
'2018-01-08 13:45:12',
'2018-01-08 14:28:34',
'2018-01-08 14:31:32',
'2018-01-08 14:31:32',
'2018-01-08 15:13:16',
'2018-01-08 15:25:19',
'2018-01-08 15:25:19',
'2018-01-08 15:25:19',
'2018-01-08 15:25:19'), "%Y-%m-%d %H:%M:%OS")),
Text=c('A', 'B', 'C', 'A', 'B', 'A', 'C', 'D', 'A', 'A', 'B', 'C')))
agg<- aggregate(df[,2], list(df[,1]), function(x) paste0(unique(x)))
Я не знаю о глобальной калиевой селитре установки, но можно попробовать это:
Do you want the files to save as UTF-8 because you are using special characters that would be lost in ASCII encoding? If that's the case, then there is a VS2008 global setting in Tools > Options > Environment > Documents
, named Save documents as Unicode when data cannot be saved in codepage
. When this is enabled, VS2008 will save as Unicode if certain characters cannot be represented in the otherwise-default codepage.
Also, which files are not being saved as UTF-8? All of my .cs, .csproj, .sln, .config, .as*x, etc, all save as UTF-8 (with signature, the byte order marks), by default.
