You didn't really provide enough detail on how you wanted the data
reshaped, but I'll take a guess:
> reshape(dat.1, direction='long',
varying=paste('X',c(0,3,6,12,25,50),sep=''), sep='')
Grp time X id
1.0 C 0 0.5326517 1
2.0 C 0 0.4715917 2
3.0 C 0 0.5021217 3
4.0 E 0 0.5845200 4
5.0 E 0 0.2985675 5
6.0 E 0 1.7854500 6
7.0 E 0 6.4370500 7
...
HTH,
