[R] create dataframe using structure ()

[Rui Barradas]

Hello,

You're misplacing one close parenthesis. See the commented lines below.


structure(list(
column_1 = 1:32,
column_2 = structure(c(1, 2, 3, 4, 5, 6, 7, 8,
1, 2, 3, 4, 5, 6, 7, 8,
1, 2, 3, 4, 5, 6, 7, 8,
1, 2, 3, 4, 5, 6, 7, 8),
.Label =
c("Unstimulated", "ESAT6", "CFP10", "Rv3615c", "Rv2654", "Rv3879",
"Rv3873", "PHA"),
class = "factor"),
column_3 =
structure(c(1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3,
3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4), .Label = c("bd", "2m", "1m",
"0.5m"), class = "factor"),
column_4 =
c(71.62097178, 2.892223468, 144.8618621, 40.90079262, 37.0516856,
32.78206822, 72.44424152, 1512.516293, 3164.748333, 1092.634557,
28733.20269, 1207.87783, 729.6090973, 151.8706088, 241.2466141,
9600.963594, 682.865522, 5869.375226, 554.8924896, 2982.759858,
7690.028092, 40.37298719, 942.3549279, 3403.679967, 103.9862389,
35.28562613, 321.5985377, 0.274424607, 3352.874906, 93.76421187,
21.3709382, 4193.183281)),  # close 2 )) here
.Names = c("row", "stimulation", "type", "copy"), row.names = c(NA,
-32L), class = "data.frame")  # and only one ) after df


Hope this helps,
