How can a function in R handle different types of input?
Hi,
How can a function in R handle different types of input?
I have written a function, which should calculate the slope from several
3-time-point measurements by linear regression
4 three-time-point-measurements:
x<-cbind(c(1,2,3,4),c(2,3,4,5),c(3,4,5,6))
time points:
time<-c(1,3,9)
function for calculating the slope by linear regression:
fit<-function(xx,t){slope <-

How to get the input of a function right?
Hi,
I wrote a function with three inputs fun(x,y,z).
x is a matrix of three vectors combined with cbind. e.g.
x1<-(1,2,3,4)
x2<-(2,3,4,5)
x3<-(3,4,5,6)
x<-cbind(x1,x2,x3)
y is a vector e.g
y<-c(7,8,9)
z is a real number e.g.
z<-2.5
If a give the function an input like this, I get 'NA' in return. If I give
the function a vector e.g c(1,2,3) instead of 'x'

Passwords issues with samba 2.0.6
In my pursuit of integrating samba password authentication with our own
stuff, I've been looking at ways on synchronizing the two. And here are
the two problems for which I hope to get either solution:
a) smbpasswd will not pass down spaces to whatever is called for
synchronization. Barely looking at the synchronization routine, it
scans as a string, which would skip anything after a space.

Building LLVM with VisualStudio 2017
Hey Bjorn,
Were you able to figure this out or is it still broken for you?
Our scenario is a little bit different, but I have a theory as to what may be going wrong. What linker are you using when you compile your project with clang-cl? I am wondering whether the version of the linker and/or the libraries that you are using is too old in comparison to the one used for the clang compilation.

Attempting to get a STELLA model into R
To whomever may be of help,
I am a student in a graduate modeling class at the University of North Carolina at Wilmington. I am trying to get a STELLA model converted into R. I am in the process of trying to 're-write' the script into R, but I seem to be missing pieces (i.e. parm values) that are keeping me from being able to replicate this model into R. Does anyone have an idea of a

Help on aggregate method
Dear R experts,
I would really appreciate if you had an idea on how to use more
efficiently the aggregate method:
More specifically, I would like to calculate the mean of certain
values on a data frame,? grouped by various attributes, and then
create a new column in the data frame that will have the corresponding
mean for every row. I attach part of my code:

A desktop Centos remix
Hello Centos users!
I'm doing a Centos 6 desktop oriented remix called Stella.
This has been brewing since the summer and it's starting to get ready. :-)
I've backported a lot of packages from Fedora and Rpmfusion and I
bundle several other repos, too, resulting in a big range of software

rank (PR#7850)
Full_Name: Stella David
Version: 2.1.0
OS: mingw32
Submission from: (NULL) (137.250.161.136)
It seems that rank doesn't work right on vectors containing negative values.
If the negative value is the first component or there are only two components,
it works, but if the negative value is somewhere in the middle there's a
problem.
Here are my examples:

Huge data sets and RAM problems
Dear all,
This is the first time I am sending mail to the mailing list, so I
hope I do not make a mistake...
The last months I have been working on my MSc thesis project on
performing data mining techniques on user logs of a
software-as-a-service application. The main problem I am experiencing
is how to process the huge amount of data. More specifically:
I am using R 2.10.1 in a laptop with

Question about difftime()
Dear R experts,
I have a question about the result of difftime() function: Does it
take into account the different number of days in each month. In my
example, I have the following:
> firstDay
[1] "2010-02-20"
> lastDay
[1] "2010-05-20 16:00:00"
> difftime(lastDay,firstDay,units='days')
Time difference of 89.625 days

When I count the days I get 88 days

Questions regarding sem using hetcor() function from polycor and diagrams
Hello R Users,
While I have attempted to dig into the R help files and I have not
identified the answer to these questions, I apologize in advance if my
questions were answered in the past. I also recognize that one of my
questions unfortunately verges on statistical rather than code
territory. I have two rather unrelated questions about using the sem and
polycor packages for a relatively

[nbdkit PATCH v2] server: Permit - in plugin names
Use of - does not need shell quoting, and aids legibility in
multi-word plugin or filter names. Permitting both - and _ would be
ambiguous (not to mention that things like 'man nbdkit-foo_bar-plugin'
would look ugly), so prefer only the character that is easier for
human use. Permitting a leading - would be ambiguous with options,
but restricting to a letter as the first character would

RFT: Use Greek semicolons for comdlg32's printer status enumeration?
Request For Translators<g>
So what I've gathered from Wikipedia is that the Greek language does not
use semicolons as a separator for enumerations:
http://en.wikipedia.org/wiki/Semicolon#Greek_and_Church_Slavonic
| In Greek and Church Slavonic, a semicolon indicates a question,
| similar to a Latin question mark.[2] To indicate a long pause or

the first name of the first column
Dear all;
I need to run heatmap. Because my first column in my data is alphanumeric,
I can not run as.matrix(scale(my_data)). So I need to make my data readable
as in data(mtcars). In *mtcars *data the first column is alphanumeric and
has no name.
Thanks,

someone help?
Here are my codes:

SPE.x<-rowSums((actual-pred)^2)
Am I missing something here?
Thanks in advance.
