Hello again,
How do I split a data frame into smaller, completely separate data frames
(rather than separate data frames comprising a single "list")? Consider the
following data, and my coding attempt:
x<- read.table(textConnection("id type number
indv.1 bagel 6
indv.2 bagel 1
indv.3 donuts 10
indv.4 donuts 9"), header = TRUE)
closeAllConnections()
x.split<- split(x, x$type)
Although I doubt it is more convenient to have so many data.frames
around (rather than having them nicely grouped in a list), you can
simply do that in a loop:
for(i in names(x.split))
assign(paste("nameOfDataFrame", i, sep="_"), temp[[i]])

This is where I'm stuck. Now I have one "list" comprised of different data
frames, but what I want is separate data frames.
Ideally, I'd like to design a loop to give sequentially-numbered names to the
separate data frames I create. This is because my real data will have many more
than two groups (i.e., many more types of things than just "bagels" versus
"donuts") and the number of groups will vary when I apply the same code to
different data sets.
Many thanks in advance for your replies!
