Eric ¿Que dataset utilizo? Por curiosidad probé su código, pero me salen errores. Copio y pego todo como me sale en la consola. > # https://raw.githubusercontent.com/datasets/covid-19/master/data/time-series-19-covid-combined.csv > datos <- read.csv("C:/Users/HP/Downloads/time-series-19-covid-combined.csv") > > library(data.table) > library(ggplot2) >

Muchas gracias a todos por su ayuda. Hace un rato antes de abrir el correo, he encontrado dos soluciones a mi problema de como calcular el porcentaje de variación. La primera es usando el paquete dplyr: https://stackoverflow.com/questions/48196552/calculate-percentage-change-in-r-using-dplyr/48196871 La segunda usando la función PercChange del paquete DataCombine

Gracias Ruben, muy interesante. Algo así estuve buscando, por ciudades y a nivel internacional, pero no lo encontré. Me bastaría con el número de fallecimientos por día, de cuantas más ciudades del mundo mejor. Si alguno supiera de algo así, le agradecería que me lo comunicase.

Hi, I am converting a data.frame to xts. ?the data.frame is 4 columns and 1000 rows. ?I get a message that "NROW (x) must match length(order.by) class is data.frame, mode is list when I run? dim(x) ? # I get? 1000 ? ? 4 ? #which is consistent with 1000 rows and 4 columns NROW (x) ?# I get 1000 ?# which is the right answer ? When I run length on each of columns in x separately using the

Dear Users, I would like to simulate an AR(1) (y_t=ct1+y_t-1+e_t) model in R where the innovations are supposed to follow a t-GARCH(1,1) proccess. By t-GARCH I want to mean that: e_t=n_t*sqrt(h_t) and h_t=ct2+a*(e_t)^2+b*h_t-1. where n_t is a random variable with t-Student distribution. If someone could give some guidelines, I can going developing the model. I did it in matlab, but the loops

Dear R-help, I am using R 2.14.1 on Windows 7. I would like to produce a plot like the attached - although simplified to actual vs. Predicted survival time with distinguishing marks for censored and observed points. I have a dataset and have fitted a Cox model to it. In an attempt to visualise how accurate the model is it would be ideal if I could plot the actual survival times against the

Hi, ? I'm trying to carry out Cramer von Mises tests between pairs of vectors belonging to a discrete distribution (concretely frequencies from 0 to 200). However, the program crashes in the attempt. The problem seems to be that these vectors only have positive integer numbers (+ zero). When I add a random very small positive decimal to the non-decimal part everything works fine (files prm1

Hi Arnaud, Hi Scott, Hi list, Here is a patch to support the Zinto D from ONLINE USV-Systeme AG. I already sent a version to Russell Kroll (2006-04-09), without no response and I cannot find support for Zinto in svn until now. I found a discussion on this list about the Xanto from ONLINE, but the Zinto seems to use different commands. The commands are quite similar to those for Opti-UPS, so I

Unfortunatly no on both counts. The arrangement right now has: PSTN Trunks & Stations <-> Nortel Norstar#1 <-CT1-> Asterisk#1 <-IAX2-> Asterisk#2 <-CT1-> Nortel Nortstar#2 <-> Stations The Asterisk boxes provide Voicemail to their sites Norstars and intersite calls over IAX. Local Voicemail works flawlessly at each site but there have been reports of PSTN calls

Hi All. I'm working on an * configuration. We require 8 inbound POTS lines, and CT1 or PRI seems like it will be quite expensive at that level. I've read that a T1 Channelbank plus the T100P would be a (the?) way to go for this situation. What is the recommended channelbank for use in this scenario? From searching the archives I see a lot of suggestions to get "a

I'm looking for a way to give VoIP capabilities to an existing PBX: it's made by Mitel and it's used in a small/medium environment (a few dozen phones, but the PBX has capabilities for up to 200, if i remember correctly). Any high-level guidelines on how to integrate Asterisk with a PBX that's already in use? Probably that particular PBX is not supported directly, but are there

Here's one last plea for help from the list before I give up on the totally cool software FAX modem concept in complete despair (for now, at least, until I have more time to dig into it).... I am simply not able to successfully receive a FAX no matter what device I transmit from or how I bring the call into Asterisk. My lastest effort was a call from a Pitney-Bowes FAX machine into an X100P

I'm just double checking.. I was told it wasn't possible but i'm going to ask just in case. Can you set outbound callerid on a channelized T1? bkw

I've noticed a problem with calls to Hangup when talking to my Norstars over channelised T-1 E&M trunk lines - it's been present since I started to fiddle with Asterisk last December and it's still present in 'Asterisk CVS-HEAD-08/13/04-10:37:13'. Specifically, when a call is connected to Asterisk from the Norstar DTI card to my T100p I get the following conditions

I would like to do a logistic multiple regression on a binary variate, with what Genstat calls an offset, ie a regression variable with the coefficient constrained=1. I'm far from home and have Splus but not R here, but any information from either source would be very welcome. I'd hate to have to go back to using Genstat . . . Thanks, Ted. --------------- Dr E.A.
