Completar un for, que falla al faltarle algún dato.
Buenas noches;
Además del proyecto que comenté antes y con el que sigo discutiendo,
también me estoy peleando con otro... con el que también tropiezo.
Necesito reordenar los datos presentados en dos columnas a filas y
columnas.
Los datos ideales serían algo así:
Ques <- c(rep("Q1",3),rep("Q2",3),rep("Q3",3))
Info <- rep(c("aca", "ahi",

Problems with "predict" function ii
I have realised that I should have used "detach" before attaching another
dataframe, but even when I do this it's still giving me lots of lines, rather
than just one:
My code:
m<-runif(1,0,1)
m
mres<-m*(seq(1,12))
mres
ssd<-rexp(1,1)
ssd
devs<-rep(0,length(mres))
for(i in 1:length(mres)){devs[i]<-rnorm(1,0,ssd)}
devs
plot(-10,-10,xlim=c(1,24),ylim=c(0,20000))

New Lemmy federated community for everything Samba (Unofficial)
Hello all,
I have taken the liberty of creating a new Samba software community over
on Lemmy. I realize that mailing lists are the traditional way projects
communicate but I wanted a place more public and easier to use. For
those who do not know, Lemmy is a federated forms platform.
Here are the links to the community:

iostat results for multi path disks
Here is a sample of running iostat on a server that has a LUN from a SAN with multiple paths. I am specifying a device list that just grabs the bits related to the multi path device:

Problems with "predict" function
Hello,
I am synthesising some sales data over a twelve month period, and then trying to
use the "predict" function, firstly to generate a thirteenth month forecast with
upper and lower 95% confidence limits. So far so good
But what I then want to do is add the upper sales value at the 95th confidence
limit to the vector of thirteen months and their respective sales to create a

frequency, count rows, data for heat map
Hi all,
I have read posts of heat map creation but I am one step prior --
Here is what I am trying to do and wonder if you have any tips?
We are trying to map sequence reads from tumors to viral genomes.
Example input file :
111 abc
111 sdf
111 xyz
1079 abc
1079 xyz
1079 xyz
5576 abc
5576 sdf
5576 sdf
How may xyz's are there for 1079 and 111? How many abc's, etc?

vector arithmetic
I'm looking for where in the source recycling and vector multiplication+addition are defined. I see some stuff in ~/src/main/arithmetic.c.
Is there anywhere else I should be looking as well?
Cheers

nchar on factors
In R 2.9.1 Windows:
> nchar(factor(paste('sdf',1:10)))
[1] 1 1 1 1 1 1 1 1 2 1
so it appears that nchar is counting the number of characters in the numeric
representation, just like:
> nchar(as.numeric(factor(paste('sdf',1:10))))
[1] 1 1 1 1 1 1 1 1 2 1
but ?nchar says explicitly:
x: character vector, or a vector to be coerced to a character
vector.

Calculate a function repeatedly over sections of a ts object
Hi,
I want to apply a function (in my case SDF; package ?sapa?) repeatedly over discrete sections of a daily time series object by sliding a time window of constant length (e.g. 10 consecutive years or 1825 days) over the entire ts at increments of 1 time unit (e.g. 1 year or 365 days). So for example, the first SDF would be calculated for the daily values of my variable recorded between years 1

Should umask takes effect when we create device file via mknod?
Hi all,
Currently, umask takes effect when we create device file via mknod, as
bellow commands show:
><fs> mknod-b 0760 8 1 /dev/sdf
><fs> ll /dev/sdf
brwxr----- 1 root root 8, 1 Apr 15 11:10 /sysroot/dev/sdf
But I wonder whether it is reasonable? For mknod(1), when we use option
-m mode, we set file permission bits to MODE, not a=rw - umask. Should
this also be applicable

Slow RAID Check/high %iowait during check after updgrade from CentOS 6.5 -> CentOS 7.2
All of our Kafka clusters are fairly write-heavy. The cluster in question is our second-heaviest ? we haven?t yet upgraded the heaviest, due to the issues we?ve been experiencing in this one.
Here is an iostat example from a host within the same cluster, but without the RAID check running:

Proper procedure when device names have changed
I am running zfs-fuse on an Ubuntu 10.04 box. I have a dual mirrored pool:
mirror sdd sde mirror sdf sdg
Recently the device names shifted on my box and the devices are now sdc sdd sde and sdf. The pool is of course very unhappy about the mirrors are no longer matched up and one device is "missing". What is the proper procedure to deal with this?

Replace NAs in split lists
Thank you Jeff. Your code works, as usual , perfectly. I am just
wondering why if i put the whole code in one line, i get an error
message.
sdf2 <- lapply( sdf, function(z){z$Value
<-ifelse(is.na(z$Value),z$Value[!is.na(z$Value)][1],z$Value)z})
error. unexpected symbol in sdf2
Thanks again

I don't know. You seem to be posting in HTML so your code is mangled. Can you post plain text and use the reprex package to make sure it produces the errorin a clean R session?
