I'd like to have two horizontal facets with multiple lines for data similar to this:
Date variable value
1 2016-08-04 sd6 0.01197055
2 2016-08-05 sd6 0.01188592
3 2016-08-08 sd6 0.01179797
4 2016-08-04 sd12 0.01263279
5 2016-08-05 sd12 0.01263080
6 2016-08-08 sd12 0.01263223
7 2016-08-04 sd24 0.01074460
8 2016-08-05 sd24 0.01074747
9 2016-08-08 sd24 0.01074515
10 2016-08-04 lcorr6 0.83422880
11 2016-08-05 lcorr6 0.83598720
12 2016-08-08 lcorr6 0.83666730
13 2016-08-04 lcorr12 0.83777470
14 2016-08-05 lcorr12 0.83803200
15 2016-08-08 lcorr12 0.83790820
Do I have to add another column to identify sd and lcorr or can I achieve this without doing so? The plot that I have in mind is something like:
Actual structure is:
structure(list(Date = structure(c(1L, 2L, 3L, 1L, 2L, 3L, 1L,
2L, 3L, 1L, 2L, 3L, 1L, 2L, 3L), .Label = c("2016-08-04", "2016-08-05",
"2016-08-08"), class = "factor"), variable = structure(c(1L,
1L, 1L, 2L, 2L, 2L, 3L, 3L, 3L, 4L, 4L, 4L, 5L, 5L, 5L), .Label = c("rollsd6",
"rollsd12", "rollsd24", "rollcorr6", "rollcorr12"), class = "factor"),
value = c(0.011970547, 0.011885922, 0.011797967, 0.012632791,
0.012630795, 0.01263223, 0.010744599, 0.010747466, 0.010745155,
0.8342288, 0.8359872, 0.8366673, 0.8377747, 0.838032, 0.8379082
)), row.names = c(NA, -15L), .Names = c("Date", "variable",
"value"), class = "data.frame")
