My very first loop!! I failed. May I have some start-up aid?
Thank you for providing the example code... for the request of running it
multiple times it would have helped if you could have confirmed that the
example ran through without errors... there were a lot of mistakes in it.
Look into using the reprex package to check your example next time.
I don't do this kind of analysis... I really don't know what to expect
from the functions. The

R OS X
Hi,
with newest R.app (1.11) / R2.1.0a
if a package is installed for the current user, it is not installed
properly (does not get an installed version entry and is not
loadable). If installed system wide it works.
The package I installed is xgobi.

find date between two other dates
Hi,
I am trying to assign "Season" values to dates depending on when they occur.
For example, the following dates would be assigned the following "Season"
numbers based on the "season" intervals detailed below in the code:

Bayesian mixing model
Fellow R users,
I'm using the BCE {BCE} function to run a Bayesian sediment mixing model. The aim is to find the optimum % contribution from each of the 4 source areas that can yield the target geochemistry.
I have geochemistry for 4 source areas called Rat:
Rat<-read.table(text="CaO MgO Na2O Al2O3

Sweeping a zoo series
Given a long zoo matrix, the goal is to "sweep" out a statistic from the
entire length of the
sequences.

lm() on a matrix of zoo series
I have a matrix of zoo series. each series is in a column.
x <- as.yearmon(2000 + seq(0, 23)/12)
# 24 months of data, lets make 20 sets of random data
testData <- matrix(rnorm(480),ncol=20)
# make a zoo object and columns will hold the 20 series
TestZoo <- zoo(testData,order.by=x)
# now run lm for just one series.
m <- lm(TestZoo[,1]~time(TestZoo))$coeff[2]

Noobie question on aggregate tapply and by
I have a 43MB dataframe ( 5 variables) and I'm trying to summarize subsets
of the data.
I've RTFM ( not very clear) and looked at a variety of samples but cant seem
to figure out
how to make these functions work.
A sample of what I want to do would be this:
ids<-seq(1,50)
years<-c(rep(5,10),rep(6,10),rep(7,10),rep(8,20))

nested 'by'
Assuming a data frame or matrix with two columns representing variable that
you want to aggregate over.
you want to calculate column means, by year, for each Id
example<-data.frame(id=c(rep(12345,5),rep(54321,6),rep(45678,7)),Year=rep(seq(1900,1902,by=1),6),
x=seq(1,18,by=1),y=seq(18,1,by=-1))
example
id Year x y
1 12345 1900 1 18
2 12345 1901 2 17
3 12345 1902 3 16
4 12345
