Hello,
I would like to ask for some advice in reformatting a data frame such as
the following one:
gIN <- c("A_1","A_2","A_3","A_4","B_1","B_2")
bc1 <- c(1219.79, 1486.84, 1255.80, 941.87, 588.19, 304.02)
bc2 <- c(319.79, 186.84, 125.80, 94.87, 1008.19, 314.02)
group <- c("A","A","A","A","B","B")
ex <- data.frame("gIN" = gIN, "bc1" = bc1, "bc2"=bc2, "group" = group)
> ex
gIN bc1 bc2 group
1 A_1 1219.79 319.79 A
2 A_2 1486.84 186.84 A
3 A_3 1255.80 125.80 A
4 A_4 941.87 94.87 A
5 B_1 588.19 1008.19 B
6 B_2 304.02 314.02 B
I would like to reshape this data frame where all the columns that have
bc1, bc2,...etc are merged into a single column (call it bcX or something)
and the other variables are kept apart, the example solution follows:
> ex_reshaped
gIN bcX group
1 A_1 1219.79 A
2 A_2 1486.84 A
3 A_3 1255.80 A
4 A_4 941.87 A
5 B_1 588.19 B
6 B_2 304.02 B
7 A_1 319.79 A
8 A_2 186.84 A
9 A_3 125.80 A
10 A_4 94.87 A
11 B_1 1008.19 B
12 B_2 314.02 B
Does anyone know of a package, and/or command to accomplish this?
Thank you
