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?
