List to a summary table
Hi
Suppose you have the code below. The result I get from the cat function is
from the avgs object. Now, I have 30 diferent objects like this and I wish
to make a summary table, something like:
Avgs1 Avgs2
Avgs3
i= 2 average= 0.515983i i= 2 average= 0.746983 i= 2
average= 0.2665983
i= 3 average= 0.5135953 i= 3 average= 0.7345953 i= 3

Means do not tally
...my experiment, I expose 10 subjects to 24 different conditions of
stimuli. Each condition is exposed to the same subject 3x.
This would make each subject have 24x3=72 data points. All the subjects
combined would have 72x10=720 data points with each condition having 30
datapoints.
To find the grand average of each condition, I find the average of all the
datapoints for a given condition.
To find the SD for each condition, if I use the raw dataset (720 datapoints)
it would not reflect the SD across subjects. Therefore, I compute the
average for each condition per subject .i.e. For subject 1, I would...

Sendmail burst of "rejecting connections" - why?

14-minute burst of sendmail activity exists in isolation.
Can anyone suggest a reason for these log entries?
Thanks.

Moving average
Good morning all!
I am attempting to superimpose a moving-average smoother onto a graph of
daily plots. These plots (in table[,2] below) span about 350 days and
looks very noisy. I'd like for this smoother to plot the average of each
group of 7 consecutive days (weekly) and show a line which joins these
series of averages. Given the definition of MA, the f...

About the statistics for ratio comparison
Hi
I have a table with four columns and 3 rows. I calculated the average for
each columns as average (A), average (B), average (C) and average (D), then
calculate the relative ratio as average (A)/average (B), and average
(C)/average (D). I would like to know how can I calculate the significance
between the two ratios.
Thanks,

Producing a SMA signal when closing price is above the moving average for 3 days
I have loaded price data for GE and then calculated a 50 day simple moving
average. Then I have a created a ifelse statement that produce a 1 when
GE's closing price is above the simple moving average and a 0 when GE
Closing price is below the 50 day simple moving average.
However, what I really want to do is to produce a 1 for when the price is
above the simple moving av...

Model averaging en R
Hola a todos,
He realizado un dredge (para obtener todos los modelos GAM posibles a parir
de un full model), luego he seleccionado un confidence set (los modelos que
no se diferencian en 2 en AIC) y he hecho un model averaging con ese
confidence set. Ahora me gustaría aplicar ese modelo "average" ajustado
sobre otro set de datos pero no se como especificar en R que use el mismo
modelo average en otro set de datos.
tanto el dredge como el model average lo he realizado con el paquete MuMIn
Alguien me puede ayudar?

Average of data files in a directory

(element-wise) of two data vectors. However, I can't work out to compute the
average when you have many data vectors in a directory. I have done this:

averaging two tables (rows with columns)
Hi R user,I am struggling to figure out on how I can calculate the average from the two tables in R. Any one can help me? really your help would be grateful- I am spending so much time to figure it out. It should not be so hard, I think.
I have very big data but I have created a hypothetical data for simplification.

Averaging across rows & columns
I use Windows, R version 2.4.1.
I have a dataset in which columns 1-3 are replicates, 4-6, are replicates,
etc. I need to calculate an average for every set of replicates (columns
1-3, 4-6, 7-9, etc.) AND each set of replicates should be averaged every 14
rows (for more detail, to measure fruit color using a spectrometer, I
recorded three readings per fruit -replicates- that I need to average to get
one reading per fruit; each row is a po...

calculating average ratings and other imponderables
...ead if it is:
Assume that a smart has_many ratings, and a rating belongs_to a smart (the
models are fine). Each rating has a column smart_id.
Each smart, then, has many ratings, with a column called "rating" that is
an int (1-10).
I want to find, say, the ten smarts with the highest average rating.
Calculating an average is easy enough--once I know which smart I''m looking
at. But how do I find this on the fly?

Averaging 'blocks' of data
Dear all,
I have a large dataset which I hope to reduce in size, to make it more useable. I hope to do this by taking an average of each 60 x 60 blockof values and forming a new data frame out of the averaged values.
How would I go about taking averages of 60 x 60 'blocks' in R, and cycling through the whole dataset, recording each calculated value in a new table/data frame?
Many thanks for any advice offered.

How to "bin"/average" time points?
...e. I am doing my PhD at The Max Planck Institute of Immunobiology where I
am analyzing some calorimetry data from some mice.
I have a spreadsheet consisting of measurements of the respiratory exchange
rate at different time points measured every 9 minutes over some days.
My goal is "bin"/average the time points of each hour to only one
measurements.
E.g.
[Time] - [Measurement]
12.09 - 0.730
12.18 - 0.732
12.27 - 0.743
12.36 - 0.757
12.45 - 0.781
12.54 - 0.731
--> should be averaged to fx one time point and one value, fx:
12.30 - [average of the six measurements]
I know how to average...

Averaging uneven measurements by time with uneven numbers of measurements
I have a new device that takes measurements anywhere from every second, to
every 15 minutes (depending on changes). The matrix has a date, time and Y
column (Y is the measurement). For three days it is 25,000 rows. How do I
average the measurements by every 30 minutes so my matrix is 48 rows per
day? I have been working on this and cannot figure out a simple method. Any
ideas? Thank you.
