Buenas, A ver si alguien sabe como hacer lo siguiente: Tengo un df con letras y numeros, quiero que si me detecta un numero en concreto me a?ada dicho numero en otra columna. Algo asi df<-data.frame(c("AV 23","PEPE 34","QWE","AV 24","WERRR ER34","AV 25")) colnames(df)<-c("nombre1") df[grepl("AV

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

Hi guys, I have been running icecast and ices for streaming mp3 around my house for about 3 months now with no problems. now all of a sudden, I get login failed when I try to run ices. nothing has changed that I know of (I am the only person with access). I seem to remember this happened when I originally installed the system, but it was all so traumatic, I kinda forgot whjat I did :) any help

Is it possible to somehow meter and log the bandwidth used by individual mountpoints? I'm using mrtg to monitor the whole server, but I'd like to know which mountpoints are creating the most traffic so I can offer better-priced streaming packages to users who really aren't using all that much bandwidth. And also to be able to charge more for users who use way much more bandwidth than

I just got Samba + LDAP up and running as a PDC. If I list the users in the LDAP directory with pdbedit -L I see: root:0:test nobody:99:nobody aster$:1001:Computer toast$:1002:TOAST$ fordprefect:1003:Test Account Shouldn't there be an Administrator account and no root? I don't want my Linux root account even remotely confused or associated with a Samba/LDAP

Hi, how are you? I have 1000 total columns with 100 rows and I have shown 4 columns of 100 rows below. I want the zeros to be read in as numerical or integer values rather than a character. Right now I have a 100x0 character matrix rather than a 100x1000 double matrix. What do I need to do to read in a .csv spreadsheet with counting the zeros as a numerical or integer value? Thank-you.

The one I like: http://www.rhetorical.com/cgi-bin/demo.cgi is toast. I think they went broke or got aquired by someone. Also, is there a Festival voice that sounds as good as Rhetorical or the AT & T stuff? The default one is barely legible. Since Festival is a little brutal to configure, I'd like to get someone's recommendation then go through the pain of reconfiguring it only once.

# grub.conf generated by anaconda I recently tried installing xen on another machine and I''m getting the "CPU0 is toast rebooting in 5 seconds" message. Reading through past postings, I was hopeful setting the dom0_mem=128M would solve the problem. Unfortunately, it didn''t make a difference. I haven''t fooled with anything on this system -- just a fresh FC4

Hi, Can someone point me to a step by step tutorial to install a postfix toaster? Thanks

Hi, I need help debugging a problem a problem that only shows up on PowerPC with one of my commits in the generic CodeGen parts of llvm.

Hi all, I have evaluated Polly's performance on LLVM test-suite with latest LLVM (r188054) and Polly (r187981).  Results can be viewed on: http://188.40.87.11:8000. There are mainly five new tests and each test is run with 10 samples: clang (run id = 27):  clang -O3 pollyBasic (run id = 28):  clang -O3 -load LLVMPolly.so pollyNoGen (run id = 29):  pollycc -O3 -mllvm -polly-optimizer=none

Everything builds fine on sparc. The configure script needs to be fixed though (see previous email).

Dear All, Suppose I have a categorical variable a=as.factor(sample(1:3,10,replace=T)) plot(a) and hist(as.numeric(a),freq=F) would give the histogram of it. But I do not know how to add the counts or percentage information for plot.factor(). hist() can do it but as a numeric variable, the x-axis is not 3 categories in this case. Thank you for any suggestion. Best wishes, Jie

ok, while i was in the process of writing that last post, fletcher and john weighed in themselves. that's good. i can say some things that they can't, though, so i will. fletcher told you how multimarkdown is booming, and it was an impressive list. what you might not realize is, he _undersold_ it. it is even bigger than he described, and it's gonna _double_ in size in the next
