I have over 8000 time series that I need to analyze and forecast. Running 1500
takes over 2 hours using just ETS, let alone Holt-Winters and ARIMA. So I am
looking at ways in shrinking the time to generate a 2 year forecast.

Informally abbreviating data is not recommended... I faked some, but would
appreciate if you would make your example reproducible next time.
All I really did for performance was use the data you read in rather than
re-scanning the file.

The first step to making things easier to do is to put those data.frames
into a list. I'll call it DFS and your data.frames will now be DFs[[1]],
DFs[[2]], ..., DFs[[length(DFs)]].
DFs <- la
Hi,
I have some very large (~1.1 GB) output files from a groundwater model called
STOMP that I want to read as efficiently as possible. For each variable there
are over 1 million values to read. Variables are not organized in columns;
instead they are written out in sections in the file, like
Dear all,
I was able to create 102 distinct dataframes (DFs1, DFs2, DFs3, etc) using
the assign() in a loop.
Now, I would like to perform the following transformation for each one of
these dataframes:
df1=DFs1[1,]
df1=df1[,1:3]
names(df1)=names(DFs1[c(1,4,5)])
df1=rbind(df1,DFs1[c(1,4,5)])

If you just want to install the package from github, the easy way is to
first install the devtools package and use the install_github function.

Dear Ron,
What about this?
set.seed(123)
d <- 4
x1 <- sample(0:1, d, TRUE)
x2 <- sample(0:1, d, TRUE)
x1
x2
expand.grid(x1 = x1, x2 = x2)
See ?expand.grid for more information.
Best,
Jorge.-

Hi all,
I want to know, where i can find a package to simulate the functions
"Search and Replace and "Find Words that contain - replace them with...",
that we can use in EXCEL.
I've look in other places and they say: "Reshape2" by Hadley Wickham. How
ever, i've investigated it and its not exactl
Hi,
Let say I have 2 binary vectors of length 'd', therefore both these vectors can
take only 0-1 values. Now I want to simulate all possible pairs of them.
Theoretically there will be 4^d possible pairs.
Is there any R function to directly simulate them?
Thanks for your help.

Hi Ryan,
It does work, but the *apply family of functions always pass to the first
