Data frame to list
I'm hoping this is an easy problem that I'm missing something obvious. Given:
x=c(1,1,1,2,2,3,3,3)
y=c(1:length(x))
dataframe=data.frame(x,y)
I would like to convert this to a list for use with certain functions,
where each entry of the list is a subsetted dataframe based on
dataframe$x
I can do this "brute force" by a for-next loop:
unique_x=unique(dataframe$x)
