before, and all I've been able to find is data. At first, I thought that was
all that had ever been there. But when I got to the end of The R Book the first
time, I noticed a statement indicating that
I'm not completely sure what your test setup does, but wouldn't it be
simpler to take a moving average at every point, but set the window
dynamically to be over the previous hour?
In pseudocode, for the j-th sample:
meanval[j] - mean(Value[ DateTime[(DateTime-DateTime[j])0
Dear R community,
I have one function, it works for small data set, but does not work on large
data set, can anyone help me with this?
#creat new variable by dividing each aa dimer by total_length.
imper-function(x, file) {
+round(x/file$length, 5)
+ }
I think that your object exceeds the limit of 2^31 elements.

Dear R community,
I write about R every weekday at the Revolutions blog:
http://blog.revolutionanalytics.com
and every month I post a summary of articles from the previous month
of particular interest to readers of r-help.
In case you missed them, here are some articles related to R from the
month of November:
Hi Josef,
is there any particular reason why you want to use your own function?
Have a look at the stats functions or special timeseries functions for
R. I am sure you will find something that calculates an ordinary moving
average (and a bunch of fancier stuff).
'filter' (stats) for example
Hello Mark,
This is how I do it but it's longer than your code :)
unique.rows - function (df1, df2) {
# Returns any rows of df1 that are not in df2
out - NULL
for (i in 1:nrow(df1)) {
found - FALSE
for (j in 1:nrow(df2)) {
if (all(df1[i,] == df2[j,])) {
found - TRUE
Hi,
I would suggest two things:
1. Use a subject related to your problem when posting to the list!
2. State a question (as Sarah has already said)!
Like this nobody can really understand what you want (or at least I cant!).

probabilities of the classification for the test set based on distances from
the classification planes? This seems possible in Linear Discriminant Analysis

Dear David,
I also use the build-in editor and textwrangler. How can I get the syntax

Hi All,
First let me state that I did search for a while on r-help, google, and
using the sos package inside of 'R', without much luck. I want to know
how to create a univariate time series from a set of data that will have
huge time gaps in it. For instance, here is a snapshot of a piece
1 - 100 of 125 matches
