I don't understand most of what you wrote, but when you say "matrix" you are
mistaken. A matrix is NOT the same thing as a data frame, which is what you get
when you call read.csv(). Read

Hi R support group
I have an experimental data of a network analysis problem. One group is

treatment of three factors are measured in ordinal scale and the other two
factors in continuous scale.

I'm trying to run Krippendorff's alpha for data consisting of 4 subjects
rated on 6 events each by three raters. The ratings are interval ratio

Dear list users,
I am looking for a R package implementing a multinomial logistic
regression with fixed effects (Chamberlain 1980, Review of Economic
Studies 47: 225–238).
Over the years, a number of questions have been asked in the R help
and in stack-related websites in order to find how to use
Dear R users;
I am trying to extract the X and Y coordinates of a polylines along with
Elevation data. I have extracted the Elevations as Z, but I do not know how
to extract the X and Y of these Elevations. Is it possible to extract X and
Y of the Elevation and create a data frame with three variab
I haven't found much call to mess with this, but I think the built-in
"glm" function could do it. You might have to reformulate the inputs to
outcome/observation (ratio) and outcome+observation (weight) to get glm to
accept it [1]... but I am not sure. What I am somewhat more sure of is
that y
I have no idea what you mean when you say "select starting date and ending
date properly form [sic] datai$DATA". For one thing there is no column
called DATA, and for another I don't know what starting dates and ending
dates you might be interested in. If you need help to subset by time,

Dear Jeff, Dear Rui, Dear all,
I will try Rui's solution as soon as possible.
If I could ask:
As a first step, I would like to follow Jeff's suggestion. I will represent
the precipitation data with a cumulative distribution, one for each year.
This follow that I would like to select the starting

Thanks a lot for your stellar replies!
They address my questions perfectly.

Very succinct, Rui!
One warning to Diego automatic data recorders tend to use the local

Hello,
See if the following can get you started.
It uses package CRAN zoo, function as.yearmon.
dati$MES <- zoo::as.yearmon(dati$DATAORA)
PMES <- ave(dati$PREC, dati$MES, FUN = cumsum)
plot(dati$DATAORA, PMES)
Hope this helps,

Are you looking for a plot where each point represents a month? Or a plot
where each point represents the accumulated precipitation so far that month?
The latter seems closer to your computations so far, but doesn't seem like a
typical way to present precipitation data...
