Returning Variables in R to Linux Shell
If I have an R script that I am executing from a command line in linux,
do you know how I can return the value of the variable in my R script to
the linux environment without writing it to a file in my R script and
then reading the file through cat?
For example, if I had a simple one line R script that just did
string <- 'TEST',
when I call

Command Line Arguments
Do you know to pass named command line arguments into an R script?
I have used littler and argv to pass a vector of arguments, but this
requires you to maintain the order of the arguments.
I'm wondering if there is a way to do this when you do not know the
order of the arguments being passed in.
Thanks,

Problems coercing to timeSeries
Hi all. I'm suddenly having problems with the following:

timeSeries and optional S4 slots?
Question on timeSeries and S4 classes:
Consider the following:
library(timeSeries)
data <- rnorm(5)
treg <- ts(data, frequency=4)
t1 <- timeSeries(data, as.Date('2010-04-15') + 1:5)
t2 <- as.timeSeries(treg)
Now both t1 and t2 are timeSeries objects, yet
t2 at ts is a valid slot, while t1 at ts is not.
Thus the ts slot is optional.
Sorry if I am misunderstanding the way S4

inconsistency between timeSeries and zoo causing a problem with rbind
Dear R Users and maintainers of packages zoo and timeSeries,
I believe there is a recently introduced inconsistency between
timeSeries and zoo which is causing a problem with rbind. I had
previously reported that I was having problems with rbind in the
following code:
library(zoo)
foo<-zoo(1,order.by=as.Date("2007-10-09"))
bar<-zoo(2,order.by=as.Date("2007-10-10"))

getting a timeseries element into a string
I have a timeseries object, ts, and want to get the first date in the series
into a string so I can concatenate it with a SQL query. Input and output are
shown below. I must be missing something very basic, but I can't seem to
pry the data ("2008-07-01") into a string variable. Any suggestions would
be appreciated.
Thank you,

Problem converting zoo object (daily data) to a timeSeries object
When I try to convert the zoo object to a timeSeries object, which would
allow me to utilize Rmetrics packages, I get an error message.
> Data<-read.zoo("c:\\DOWUBSPRICING.txt,na.strings="NA",sep="\t",header=T)
> is(Data)
"zoo"
> as.timeSeries.zoo(Data)
Error in .local (.Object, . )
Is this happening because I am using daily data?

modeling interval data, a.k.a. irregular timeseries
Greetings -- I've got some sensor data of the form
t1_1, t1_2
t2_1, t2_2
...
tN_1,tN_2
-- time intervals measuring starts and stops of sensor activity. I'd
like to see whether there's any regularity in it. Seems natural to
consider these data timeseries -- except most of the timeseries
packages and models assume regular ones, with a fixed frequency.

Criteria for individually adressing data ranges within timeseries data
Dear R-Users,
my dataset contains timeseries that are structured into task-specific
epochs as labelled by a factor and a boolean variable for labelling each
data-point within the series as artefact or non-artefact.
Now there's no problem in addressing continuous task-specific
time-series that are free from artefacts as long as artefacts extend to
either boundary of adjacent timeseries but

[R-SIG-Finance] FinCenter in timeSeries with "merge", "cbind" and "rbind"
Hi R users:
When I try to merge or bind (cbind or rbind) two series,

result is "GMT" not the original financial center?
What am I doing wrong?

ts & daily timeseries
I have defined a daily timeseries for the 365 days of 2003 issuing:
myts = ts(dati[,2:10],frequency=365,)

Time Series:
Start = c(1, 1)
End = c(1, 365)
Frequency = 365

How can I combine mytime and myts in order to list

Creating Timeseries by manipulating data table
Hi,
I'm new to R and tried a search but couldn't find what I was looking for.
I have some data as a csv file with columns:-
longditude latitude year month rainfall region
What I need to do is produce a monthly time series for each region, where
region is an integer id and where each time point in the series is the
monthly average of rainfall for each location in that region.

R 3.5.3 having trouble spawning a new process on my Windows 10 machine
Hi all,
I am noticing some strange behaviour so I am bringing to this list. In the

Research assistant at University Bremen, Germany: Timeseries Analysis with R
Hi there,
we are looking for a research assistant for a project on analysing
timeseries in the field of educational research.
We have timeseries of the subjective perception (I understand, I feel
good, I am interested etc.) of 109 students (6 different courses, 26
to 72 hours of classroom teaching, 208 to 332 points of measurement).
We want to do exemplary analysis of the interaction

I try to calculate the correlation between macroeconomic data from

However, since the timeseries are not in synch, the correlation fails.

Ggplot and irregular timeseries
Hello there,
Could anybody please help on how to correctly use ggplot when
printing irregural time series, by irregural here I mean for example
the absence of some dates in the whole timespan of a dataset. To be
more precise in the following example I generated some random data
which spans the whole November up to now and dropped weekend days but

Change font size in Windows
My day for dumb questions. How do I increase the type size in the Rgui console in Windows? (R-2.13.0, Windows 7)
It looked to me that I just needed to change the font spec in Rconsole but that does not seem to be working.
The R FAQ for Windows has a reference in Q3.4 to changing fonts, (Q5.2), but I don't see anything relevant there.
Rconsole originally was:

character to time problem
I am trying to clean up some dates and I am clearly
doing something wrong. I have laid out an example
that seems to show what is happening with the "real"
data. The coding is lousy but it looks like it
should have worked.
Can anyone suggest a) why I am getting that NA
appearing after the strptime() command and b) why the
NA is disappearing in the sort()? It happens with
na.rm=TRUE
