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 = "ZZZ", damped = NULL) Smoothing parameters: alpha = 0.5901 beta = 0.0058 gamma = 1e-04 Initial st...

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.

Dear list members, I am analysing my microarray data using limma package. Now I encounter several problems. Looking forward to your suggestions! Question 1: During the process of background correction using method="normexp", four warning messages appeared as "NaNs produced in: log(x)" (as you can see in the program posted below). What does that mean? How will it effect the

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:

...registered on an ip400 Gatekeeper which routes every call to asterisk, and asterisk processes the Dialplan and sends the call back to the ip400 and to the correct Endpoint. With this configuration the Endpoints can dial each other above the Gatekeeper and Dial Plan. ;-) well pretty fine - the only damped thing is every call loses connection after 30 sec because of a a H323 control protocol error . this is the asterisk output while phoneing : ############################################################################### *CLI> -- Executing Dial("OH323/R1", "OH323/402...

I actually forgot to mention that I'm using ultra-wideband mode, but seems like you understood that anyway. Is this true that Speex echo cancellation only performs well in narrowband mode !? I've been using 100 ms as the default tail length. I don't know what the ideal tail length would be. I have tried shorter and longer tails but it hasn't made any difference. Does

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",

Ok, let me be more clear on this. AFAIK, Windows OS doesn't expose speaker input as other OS ( Linux, Mac OS...). That puts you in bad spot in using Speex AEC with windows. Only way to work is to use Soundcard with ASIO functionality which does give you speaker input. But then you would have to impose that requirement on all your users. I heard Speex AEC works great from developer who

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
