error: unused arguments
Hi
what does this mean when i get above error? When I call function foo(),
specifying parameters a and b as below
a<-5
b<-6
> y <- foo(a,b)
> Error in foo(a, b) : unused argument(s) (6)
Thanks

vertically concatenating data frames
Hi,
what is the recommended way to vertically concatenate 2 data frames with
the same column names but different number of rows?
My problem is something along these lines:
df1 <- data.frame(var1=var1,var2=var2,var3=var3) # nrow(df1)=1000
df2 <- data.frame(var1=var4,var2=var5,var3=var6) # nrow(df2)=2000
I tried df <- c(df1,df2), no success. stack does not seem to be
appropriate

lead
Hi,
is there any function in R that shifts elements of a vector to the
opposite direction of what Lag() of the Hmisc package does? (something
like, Lag(x, shift = -1) )

poor rbind performance
Hi
I rbind data frames in a loop in a cumulative way and the performance
detriorates very quickly.
My code looks like this:
for( k in 1:N)

filename <- paste("/tmp/myData_",as.character(k),".txt",sep="")
myDataTmp <- read.table(filename,header=TRUE,sep=",")
if( k == 1) {
myData <- myDataTmp

compute time span in months between two dates
Hi,
I am just starting to play with R. What is the recommended manner for
calculating time spans between 2 dates? In particular, should I be using
the "chron" or the "date" package (so far I just found how to calculate
a timespan in terms of days)?
Thanks

converting list to an array
Hi,
I have a list myList (see below) that consists of id's $'7',....,$'10'
and each id has an individual array, the length of which can vary from
id to id.
How can I convert this list into an array, ie. stacking the individual
arrays into one large array?
Thanks
Zava
myList:
$`7`
[1] 20050201 20050301 20050401 20050501

Elegant way to transform dataframe?
Hello,
I have a dataframe with columns like:
parameter1 parameter2 metricname value
and I'd like to transform it into a dataframe with columns:
parameter1 parameter2 metric1 metric2 metric3
where the values for each metric would be in the appropriate column. There are often multiple values for a given (parameter1, parameter2, metricname) triple. In this case, I want to use the

'fixing' list components
I have a list x (say) that will contain many inputs to and outputs a model.
x$input1 <- assign.input1(parameter1, parameter2)
is one way to assign input1, but it would be neater to be able to do
assign.input1(x, parameter1, parameter2)
Is this a good idea? If so, what is a good way to do it?

basic handling of data.frame
Hello,
I'm new to R but wan't to use it to compute the statistics of my medical study.
The study includes several parameters for a number of patients. Each
parameter was assessed by a number of readers, once with a special
condition, once without.
Now I have a data.frame with colums like:
PatientID, ReaderID, SpecialCond(yes/no), Parameter1, Parameter2.....

Class parameter flexibility with ENC, hiera or both
Dear puppetteers,
I am having a philosophical question about parametrized classes.
When building modules, one wants to be as flexible as possible, to try
to target as many puppet flavors as possible. This is our target:
- Foreman users, using foreman as an ENC with smart variables (or
potentially any other ENC, but I would say this is the most widespread one).
- Pure Puppet''s site.pp

A statement over multiple lines (i.e. the ... feature in Matlab)
Hello again list,
I thought I'd start a new thread, seeing as it's completely different
from my previous question. Some functions I have written require many
parameters, and so do not fit nicely into an 80 column width display.
This is usually avoided, by spreading that particular statement over
a few lines. This is something that I do in Matlab with the following:

[LLVMdev] object construction patterns and unique_ptr
In lld we have a Reader class which is a factory that takes .o file(s) and produces an in memory lld::File object(s). But in doing so, there could be I/O errors (file not readable) or file may be malformed. We are also using C++11 in lld, so we use std::unique_ptr for managing object ownership.
The Reader class currently has an interface that can be simplified down to:
virtual error_code

structure data
Hello,
I have a quite simple question, I guess. I have a data frame and I would like
to process the data in several ways.
The processing is dependent on grouping (factors) and the parameter itself.
Meaning for parameter1 in the df, I would like to calculate the mean and sd
when grouping by factor1. But parameter2 might be different. I thought of a
structure like this:
group1
param1
