Dears,
The arrows command uses the start and end coordinates of each vector, but I
have the starting coordinates, azimuth, and length.
So, There are package that plot this arrows?
Example:
> x<- c(1,2,4)
> y<- c(2,3,5)
> Azimuth<- c(45,90,180)
> Length<- c(1,0.5,1)
Thanks,
Julio

Hello,
we are collecting information on the subject of research data management
in German on the webplatform:
www.forschungsdaten.info
One of the topics, which we are writing about, is how to *archive* data.
Unfortunately, none of us in the project is an expert with respect to R
and so I wo

Dear fellow R users,
valaddin (0.1.0) has been published on CRAN:
https://cran.r-project.org/package=valaddin
Using valaddin, you can transform an existing function into a function with
input validation, without having to rewrite it with stop() or stopifnot()
statements. It therefore provides a c
Apologies; 'length' is an arrows() argument. Use something else - see below.

May be packages out there but if it's a quick fix you want, roll your own.

1. This may be the wrong forum for this question, as this list is
about R programming issues. However, I don't know what the right forum
should be. You might consider stats.stackexchange.com. Some IT forum
might be better (but which???)
2. A google search on "data formats for archiving" (or
Dear Joe,
I'd choose a plain text format. They can be read and parsed with a
very wide range of software. That is IMHO a much more important factor
for long term archivation that file size or the ease to read it with
specific software.

I have a project with a connection that was working properly on the same

I suddenly got the error below. However, I could connect from the same

Hello everyone,
Hope you are all doing great. So I have two datasets:
-dataset1Frame: which contains the historical number of transits from
october 1st, 1985 up to march 1, 2017. It has two columns, one called
TransitDate and the other called Transits. dataset1Frame is a table comming
from an SQL
II find using complex numbers makes for less typing with
this sort of thing. Note the use of plot(asp=1,...) to force
equal scales on both axes so the angles are right.
(I think asp=1 should have been the default when plotting complex
numbers, but too late now.)

The relevance to R (and therefore R-help) of this question is marginal at best.
R might not be the language of choice when you go retrieve the data.
Also, this question seems dangerously close to a troll, because the obvious
answer is that the data should be in an open format but if you are not
Hi Julio,
Perhaps "vectorField" (plotrix) is what you are looking for.

Hi Bruce,
Before we get into the whole business of why your CSV file is lying by
the side of the road to the R help list, let's deal with a few more
important things.
1) You have created a data frame "dd" by reading your CSV file (we hope).
2) You have then overwritten this with two vectors (?) o

first of all when you read the data in you get 379 rows of data since
you did not say 'header = TRUE' in the read.table. Here is what the
first 6 lines of you data are:

Hello everyone,
I have general question about parallel programming. I'm doing simulations
that involves bootstrap. For now I'm using parLapply only for bootstrap
part and then function "replicate" for simulations. It is very long
function, so here is a short version:
simfun=function(data,n,alpha
Let's say I have repeated measures of some outcome on some subjects. I
want to be able to calculate the within and between subject coefficient of
variation for this measure.
An example data frame is:
df<-data.frame(ID = c(1,1,1,2,2,2,3,3,3),
DAY = c(0,3,6, 0,3,6, 0,3,6),
21 matches
