A basic question about reshape2
2 messages · Jim & Carolyn Watkins, John Kane
I am not sure about this but I don't see how a melt command helps. See what z = dcast(x, I ~ V, mean) gives you.

Dear R Community:
This is a newbie reshare2 question; it starts with read a
set of data and to
melt it:
x = data.frame(I=c("a","b","a","b","b"), V=c(2,4,2,5,7))
y = melt(x, id = 1:1)
What is wrong with the final dcast step:
z = dcast(y, formula = I ~ "variable",? c(length,
mean, median))
Will one of you please help me with this problem?
