HI,
Try:
library(reshape2)
melt(data,measure.vars=c("t1","t2"),var="ind")

I was just wondering how to stack values of columns to rows. Would you give me
some idea how I can stack? I just want to stack columns 2 and 3 but not
column1. The column 1 is supposed to be repeated. I was able to stack using
"stack" but I could not repeat the column 1.
For example I have data like this
group t1 t2 t3
101 -31.77083 -33.79167
103 -27.26667 -27.9
data<-structure(list(group = c(101L, 103L), t1 = c(-31.77083, -27.26667
), t2 = c(-33.79167, -27.9)), .Names = c("group", "t1", "t2"), class =
"data.frame", row.names = c(NA,
-2L))

Want to make like this"
group values ind
101 -31.7708 t1
103 -27.2667 t1
101 -33.7917 t2
103 -27.9 t2
final<-structure(list(group = c(101L, 103L, 101L, 103L), values = c(-31.77083,
-27.26667, -33.79167, -27.9), ind = structure(c(1L, 1L, 2L, 2L
), .Label = c("t1", "t2"), class = "factor")), .Names = c("group",
"values", "ind"), class = "data.frame", row.names = c(NA, -4L
))
I really appreciate for your help.
thanks
