combine_ranges | R Documentation |
Combines ranges from different tables into a single table.
combine_ranges( dfs, groups = NULL, start_var = NULL, end_var = NULL, startAttr = NULL, endAttr = NULL, dimension = "date", max_gap = 0L, fmt = "%Y-%m-%d", tz = "UTC", origin = "1970-01-01" )
dfs |
A list of your data frames, e.g. list(df1, df2) |
groups |
Grouping variables |
start_var |
Start of the range |
end_var |
End of the range |
startAttr |
Attributes linked to start of the range which should be kept (converted to character type by default) |
endAttr |
Attributes linked to end of the range which should be kept (converted to character type by default) |
dimension |
Indicate whether your range includes only dates ('date') or also timestamp ('timestamp'). Defaults to 'date' |
max_gap |
Gap between date or timestamp ranges, e.g. for 0, default, it will put together all records where there is no gap in-between |
fmt |
The format of your date or timestamp field, defaults to YMD |
tz |
Time zone, defaults to UTC |
origin |
Origin for timestamp conversion, defaults to 1970-01-01 |
Returns a data frame (if first table passed is data.table, then data.table) with combined ranges.
df1 <- data.frame( start = c("2010-01-01", "2012-06-01", "2014-10-15"), end = c("2010-08-05", "2013-03-03", "2015-01-01"), group = c("a", "a", "b"), infoScores = c(0, 3, 2) ) df2 <- data.frame( end = c("2012-04-05", "2014-06-09", "2009-02-01"), group = c("b", "a", "b"), start = c("2009-01-15", "2012-07-08", "2008-01-01"), score = c(8, 2, 3) ) combine_ranges(dfs = list(df1, df2), groups = "group", start_var = "start", end_var = "end")
