Something like this?
set.seed(123)
y <- rnorm(20)
sapply(1:length(y), function(x) sum(y[1:x]))
or this, depending what is the output of your custom function
lapply(1:length(y), function(x) sum(y[1:x]))

Hi Joshua, thanks for your prompt reply. However as I said, sum()
function I used here just for demonstrating the problem, I have other
custom function to implement, not necessarily sum()
I am looking for a generic solution for above problem.
Any better idea? Thanks,

Use a `width` of integer index locations. And you likely want =
"right" (or rollapplyr(), as I used).

R> x <- rnorm(10)
R> rs <- rollapplyr(x, seq_along(x), sum)
R> cs <- cumsum(x)
R> identical(rs, cs)
[1] TRUE

I am wondering there is any function for 'zoo' time series, where I
can apply a user defined function rolling window basis, wherein window
size is ever increasing i.e. not fixed. For example, let say I have

I am able to import the whole data set into R as well, and then select
the required columns. But what I am looking for is to optimize on the
run time, as I only need a few columns out of 100s.
Something similar to what fread (package data.table) provides while
importing from a CSV file.

hi, the sas universal viewer might be a free, non-R way to convert a
sas7bdat file to non-proprietary formats, not sure if it's windows-only.
those other formats should be easier to import only a subset of columns
into R..

I had a look at this a while back and it didn't seem to be easy. The path of
least resistance would seem to be to use SAS itself to create a data set with
fewer columns, but of course that requires you to get access to SAS.
Otherwise, I think you'd have to modify sas7bdat::read.sas7bdat to

If I understand you correctly you cannot just have a single predicted
curve but one for each level of your factor.

I want to import data from huge sas files with 100s of columns. The good

can you just say in a bit more detail what you want to happen -- can you

M-x ess-rdired
e.g. which buffer do you quit from, and which one (e.g. *R dired*, *R

Hi,
if I open the object view with ess-rutils-objs I would like that
pressing 'q' not only kills the buffer (which is what is done, as far
as I can see in the code), but that quit-window is executed. What would
be the best method to implement it?
Many thanks in advance.
Best,
