Creating a list to store output objects from a recursive loop
...ted two
results for each loop
The result1 is a zoo object
The result2 is a data frame
Now I want to put both of them in a list or some structure ... that I can
access or output to a file after the loop is done.
For e.g.
for (i in 1:20){
niceFunction(x[i],i)
}
niceFunction (x,i) {
result1 = someOperations() #zoo object
result2 = someOperations() #data.frame
OutputObj[i,1]=result1
OutputObj[i,2]=result2
}
How can I go about this?
Thanks,

memory, speed, and assigning results into new v. existing variable
I have a very large data frame, and I'm doing a conversion of all columns
into factors. Takes a while (thanks to folks here though, for making
faster!), but am wondering about optimization from a memory perspective...
Internally, am I better off assigning into a new data frame, or doing one of
these:
dataframe<-someoperation(dataframe)
It would seem that re-assigning into the same data
