Dear Jeff, Dear Rui, Dear all,
Forget about the monthly things. I was trying to do two things at the same
time.
I try to explain myself. Thanks for your time and I really appreciate your
help.
I have a long file with hourly precipitation from 2000 to 2018. I would
like to select only on e year o
Hello,
With on«bjects of class "Date" or "POSIXt", POSIXct" you can do
lubridate::year(date_obj)
to extract the year. Then aggregate by it.
Hope this helps,

Hi Halllie,
As Jeff noted, a data frame is not a matrix (it is a variety of list),
so that looks like your problem.
hkdf<-data.frame(sample(3:5,4,TRUE),sample(1:3,4,TRUE),sample(2:4,4,TRUE),
sample(3:5,4,TRUE),sample(1:3,4,TRUE),sample(2:4,4,TRUE))

Hello everyone,
We present you the permuco package, which has 2 main purposes: PERmutation
tests and MUltiple COmparisons.
First, the package has functions for permutation tests for parameters in linear
models with nuisance variables. Several permutation methods exist in the
literature to redu

Please click to keep this threaded.
What I was trying to say is to do something along the lines of
Y <- lubridate::year(dati$DATAORA)
Y2013 <- Y[Y == 2013]
PY2013 <- ave(dati$PREC, Y2013, FUN = cumsum)
plot(dati$DATAORA, PY2013)
Hope this helps,

Hi Jeff;
Thanks so much for this. I would try to reformulate what you suggested.
Your help is highly appreciated

I conducting epoch analysis. I tried to test the significance of my
result using randomization test.
Since I have 71 events, I randomly selected another 71 events, making

Hi all,
Thank you for your responses. You are correct that it is not a matrix. I used
the incorrect term.
I meant I put my data in a spreadsheet with three rows and 24 columns.

Hi,
I recently learned of the existence of R through a physicist friend who
uses it in his research. I've used Octave for a decade, and C for 35
years, but would like to learn R. These all have advantages and
disadvantages for certain tasks, but as I'm new to R I hardly know how

R has many similarities to Octave. Have a look at:

I would say your question is foolish -- you disagree no doubt! -- because
the point of using R (or Octave or C++) is to take advantage of the
packages (= "libraries" in some languages; a library is something different
in R) it (or they) offers to simplify your task. Many of R's libraries are

This would be a suitable application for NetLogo. The R package
RNetLogo provides an interface. In a few lines of code you get a
simulation with graphics.

S (R's predecessor) was designed by and for data analysts. R generally
follows that tradition. I think that simulations such as yours are not its
strength, although it can make analyzing (graphically and numerically) the
results of the simulation fun.

If you forge on with your preconceptions of how such a simulation should be
implemented then you will be able to reproduce your failure just as
spectacularly using R as you did using Octave. It is crucial to employ
vectorization of your algorithms if you want good performance with either

Dear R users,
Does anyone have a recommendation for an R package that can:

Gaussian)
2. Fit a latent class regression (i.e. use observed covariates to
predict latent class membership)?
3. Incorporate programs to do th
