At any rate:
Error(SUBJECT/IV)
specifies two random effects: SUBJECT and SUBJECT:IV. This is most easily
understood if you conceptually arrange your data in a SUBJECT x IV table: One
effect is a set of random errors added to each row, the other is a set of
effects added to each cell.
If you

Just use ?aggregate.
Example <- read.table(text = "

a2 0101221
a2 0112021
a3 0111111

aggregate(. ~ ID, Example , sum)

Hi Pablo,
There are probably many ways to do this in R. This suggestion uses dplyr.
The solution is actually only one line (see the line starting with dat2).
The first section simply creates the example data.
library(dplyr)
# 1. set up the example data
m <- matrix( c(0,0,0,0,0,1,1,1,0,0,1,1,1,1,2,

Hello there. Happy new year for everyone!
I need help with a table. This table contains 300 rows and 192 columns.
Being the first column the ID of my samples that can have several
observations.
I need to generate e NEW table that contains a single ID with the sum of
the observations by columns
I have recently installed R on my new computer. I also want to install
the package RQuantLib. So I run the following command and get the

Your dates have an incomplete year information with 34. R assumes that 00-68
are 2000 to 2068 and 69 to 99 are 1969 to 1999. See ?strptime and the details
for %y.
You can either append “19” to the start of your year variable to make it
completely express the year or check if the date is in the
Bert, thanks for the reply but I feel that my question is less about
statistics and more about R interface. Specifically, because the output of
R seems different than other programs (systat, for example, gives a between
and a within table instead of a three level one).

Hi all,
I’m struggling to get the dates in proper format.
I have dates as factors and is in the form 02/27/34( 34 means 1934). If I use
as.Date with format %d%m%y it gets converted to 2034-02-27. I tried changing
the origin in the as.Date command but nothing worked. Any help is appreciated.

Dear list users,
I am trying to learn Repeated measures ANOVA using the aov() interface, but
I'm struggling to understand its output.
According to tutorials on the web, formula for a repeated measures design
is:
aov(Y ~ IV+ Error(SUBJECT/IV) )
This formula does work but it returns three strata
