Dear R helpers, I have a data.frame as given below - dat1 = data.frame(date = as.Date(c("3/30/12","3/29/12","3/28/12","3/27/12","3/26/12", "3/23/12","3/22/12","3/21/12","3/20/12", "3/30/12","3/29/12","3/28/12","3/27/12",

Dear list, I'm currently facing problems when receiving eMails with attachments, at least sometimes. My mailserver is set up with the tool 'Mailcow', and hence is based on Dovecot (2.2.22 (fe789d2)) and Postfix. Usually, there are no problems with receiving mails. If a mail has an attachment, however, it is possible that the following error occurs (extract from /var/log/mail.log):

Dear R helpers Suppose I have a vector as vect1 = as.character(c("ABC", "XYZ", "LMN", "DEF")) > vect1 [1] "ABC" "XYZ" "LMN" "DEF" I want to reverse the order of this vector as vect2 = c("DEF", "LMN", "XYZ", "ABC") Kindly guide Regards Vincy [[alternative HTML

Dear R helpers   I have some variables say ABC, DEF, PQR, LMN and XYZ. I am choosing any three varaibles at random at a time for my analysis and name these files as input1.csv, input2.csv and input3.csv. So if I choose variables say ABC, DEF and PQR, I am passing the specifications of these variables to input1.csv, input2.csv and input3.csv respectively.   This means in another case even if I

I have a function that fits polynomial models for the orders in n: lmn <- function(d,n){ models=list() for(i in n){ models[[i]]=lm(y~poly(x,i),data=d) } return(models) } My data is: > d=data.frame(x=1:10,y=runif(10)) So first just do it for a cubic: > mmn = lmn(d,3) > predict(mmn[[3]]) 1 2 3 4 5 6 7 8

When I try to create a PV domU, the VM starts up and I can access it through "xm console <id>", but when I try to connect to it through VNC, the port just hangs. I''ve tried using RealVNC and TightVNC, and also tried on Linux and Windows. All that happens on the client is that it says that the connection has established, and hangs there. I''ve tried running

Hi, I am casting a dataframe from long to wide format. The same codes that works for a smaller dataframe would take a long time (more than two hours and still running) for a longer dataframe of 2495227 rows and ten different predictors. How to make it more efficient ? wer <- data.frame(Name=c(1:5, 4:5), Type=c(letters[1:5], letters[4:5]), Predictor=c("A", "A",

Hello, I came up with this scenario of the use of batch mode while thinking of back-up schemes to use for myself. However, it could be that the last step needed in this scenario is not supported by rsync! Here's the scenario: At one time, /c/home/wer/work and /e/gold had identical content and were really huge (say, 200 GBytes). After some complex, intricate work, Mr. Wer

Dear R Forum, I have a data.frame as df = data.frame(date = c("2013-04-15", "2013-04-14", "2013-04-13", "2013-04-12", "2013-04-11"), ABC_f = c(62.80739769,81.04525895,84.65712455,12.78237251,57.61345256), LMN_d = c(21.16794336,54.6580401,63.8923307,87.59880367,87.07693716), XYZ_p = c(55.8885464,94.1358684,84.0089114,98.99746696,64.71083712),

Hi there, I was looking for stack smashing protection under freebsd, so i found libparanoia (/usr/ports/security/libparanoia), i had only one question using the normal 'make install' (so no copy-to-libc). If i add in /ert/make.conf: CFLAGS= -O -pipe -lparanoia -L/usr/local/lib COPTFLAGS= -O -pipe -lparanoia -L/usr/local/lib Will EVERYTHING build from that time (including

Make sure you’re running LLVM with assertions enabled. You’ll get more information about what’s going wrong that way. That said, yes, this looks like a bug. Specifically, SelectionDAGLegalize::ExpandConstantFP() assumes that f32 is the smallest floating point constant type it’ll need to handle, and that MVT enum ordering reflects that. while (SVT != MVT::f32) {

Hi, if I write the following simple program: target datalayout = "e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-v64:64:64-v128:128:128-a0:0:64-s0:64:64-f80:128:128-n8:16:32:64-S128" target triple = "x86_64-unknown-linux-gnu" define void @foo () { %1 = alloca half store half 0xH42CC, half* %1 ; 0xH42CC = 3.4 %2 = load half* %1

Con parse_number sacaria todos los numeros de la columna, pero lo que busco es sacar solo los que empiezan por AV y descartar el resto. De todas maneras muchas gracias, le voy a dar otra vuelta. ________________________________ De: Juan Carlos Lopez Mesa <jclopez5 en unal.edu.co> Enviado: martes, 22 de septiembre de 2020 21:32 Para: Samura . <tontito82 en hotmail.com> Cc: r-help-es

Does anybody know the gnome program that you can write in latex with please? I'm not sure but I think its in the base repo. Its not winefish as it (winefish) doesn't compile the source text like the program that I'm looking for does.
