Hello:
I have a list of data frames, built like this: the second df is a result of
a function applied to the first, and so on.
So the ith df is always dependent on the (i-1)th df. I've been doing this
using for loops. However I think I have too many for loops which is making
my code run slowly.
Is there any workaround this? How can I avoid the use of for loops?
As an example:
output.list <- as.list(rep("", 100))#creation of a list
output.list[[1]] <- df1#first position
for(I in 2:100){#following positions
df0 <- output.list[[i-1]]
df0_1 <- f1(df0)#function applied to the previous df
output.list[[i]] <- df0_1#new df
}
thanks,
Frederico
