I'm not sure if this is a bug, or if I'm doing something wrong. =20 =46rom the worms dataframe, which is at in a file called worms.txt at =20 http://www.imperial.ac.uk/bio/research/crawley/therbook <http://www.imperial.ac.uk/bio/research/mjcraw/therbook/index.htm>=20 =20 the idea is to extract a subset of the rows, sorted in declining order of worm density, with only the maximum

I have 2 dataframes. "mydata" contains numerical data. "mybys" contains information on the "group" each row of the data is in. I wish to aggregate each column in mydata using the corresponding column in mybys. Please see the example below. What is a more elegant or "better" way to accomplish this task? Thanks! mydata =

Hi, I would like to create variables in R containing parameters of summary(*Forecast Results*). Using the following code: library(forecast) data <- AirPassengers xets <- ets(data, model="ZZZ", damped=NULL) xfor <- forecast(xets,h=12, level=c(80,95)) summary(xfor) the output is: Forecast method: ETS(M,A,M) Model Information: ETS(M,A,M) Call: ets(y = data, model =

Also noteworthy: the air moving through a hose can cause a vacuum's hose or attachment to build up a static charge, which is another reason it can be a bad idea to use a vacuum in a computer.

...produced in: log(x)" (as you can see in the program posted below). What does that mean? How will it effect the final result? How could it be settled? Question 2: On my microarray, every probe has two replicates.During the process of duplicateCorrelation, two warnings appear as "Too much damping - convergence tolerance not achievable" (as you also can see in the program posted below). What does it mean? Is there anything wrong with my data? Question 3: How to construct the design matrix is a puzzle to me. Here I constructed the design matrix using the function modelMatrix and the obj...

I have been trying to use the ets function in the forecast package on a daily time series (ts2 is a ts object with frequency =7). However when I run the following code I get an error related to etsmodel. I have looked at ets and I can see that there is a call to the function etsmodel, but I cant seem to find info on the ets function anywhere. Does anyone know anything about the etsmodel function?

A Polycom 550 and a IAX client (Mozphone and ZoIPer were used) are having a conversation. Call quality is reported as good except for an echo with a 3 second delay. Most of my searches are saying echo happens only on the PSTN piece, but there isn't one here. Can someone point me in the right direction?

Good afternoon! I'm trying to model a ts but unfortunately i'.m very new to this kind of modeling so i 'll be very grateful if you have an advice. This was my syntax:

Hi there ! I searched the whole web to find some helping information about H323 Control Protocol, but there is no way to find that information. We compiled and installed asterisk_0.9.0 + pwlib 1.5.2 + openh323_1.12.2 + 'asterisk-oh323_1.5 channel driver + wrapper' and configured the dialplan for using our H323 Endpoints which are ip200 Innovaphones.

Since you state that using -z is almost always a bad idea, could you provide the rationale for that? I must be missing something. ________________________________ From: CentOS <centos-bounces at centos.org> on behalf of Peter Kjellstr?m <cap at nsc.liu.se> Sent: Wednesday, March 25, 2020 9:34 AM To: Simon Matter <simon.matter at invoca.ch> Cc: centos at centos.org <centos at

I have a two question regarding the "aggregate.data.frame" method of the "aggregate" function. My situation: a. My "x" variable is a data.frame ("mydf") with two columns, both columns of type/format "numeric". b. My "by" variable is a data.frame("mybys") with two columns, both columns of type/format "character". c.

I appreciate the reply - it keeps me from wondering "is there something I should be concerned about?". We use a co-location facility where we pay for bandwidth utilization so it's still an issue. ________________________________ From: CentOS <centos-bounces at centos.org> on behalf of Pete Biggs <pete at biggs.org.uk> Sent: Wednesday, March 25, 2020 1:32 PM To: centos

GENERAL REFERENCE ON NONLINEAR OPTIMIZATION? What are your favorite references on nonlinear optimization? I like Bates and Watts (1988) Nonlinear Regression Analysis and Its Applications (Wiley), especially for its key insights regarding parameter effects vs. intrinsic curvature. Before I spent time and money on several of the refences cited on the help pages for "optim",

Sorry to keep quizzing the r-helpers but I'm having real difficulty with arima. I am happy that i have chosen the best fitting arima model for my data,(in this case arima(1,1,1) but when i use the predict function the forecast damps to a constant value after just two or three values, and from a time series of almost 3000 values i am left with only a couple of predicted values. I have tried
