Defining multiple variables in a loop
Good day,
For lack of a better solution (or perhaps I am ignorant to something
more elegant), I have been bootstrapping panel data by hand so to
speak and I would like to know if there is a way to define multiple
variables in a loop using the loop variable. I found a post (here:
https://stat.ethz.ch/pipermail/r-help/2002-October/026305.html ) that
discussed naming multiple variables but it

How to add specific column to data.set?
Hi
I have a data.set with 7 lists, with over 7000 observations in each list. to
of the lists contain country names.
like:
aus dnk
fra aus
usa aut
itl usa
.
.
.
etc.
My dilemma is that I want to add an extra column/list to my data.set. If the
countries are both european it should be assigned 1 or true AND if one or
both the countries are non-european it should be assigned 0 or false.

quotes in cat() within function
Hello all,
Sorry if this question has been answered in the past, but I could not find
an answer.
I am trying to print quotes within a cat output. The arguments are:
file= "Data labels"
directory= "/home/mylaptop/"
The function returns:
cat("The file", file, "is located in directory", directory, sep=" ")
The output R prints is

looping through numbered variables
Hello,
This is a beginner question. I am trying to loop through numbered
variables with "apply" to calculate weighted means. My data is "data",
the variables are "var1" to "var100", the weight is "weight". The
command works using
sapply(paste('data$var', 1:100, sep=''), function(x)
weighted.mean(eval(parse(text=x)), data$weight))

LMER: How to specify Random Effects
I saw different specifications for Random Effects and I'm confused about
the use of "/" and the use of "(0+...|)" .
Let say we have a nested structure where some countries have some
several plants in different states and we measure the reaction to a drug.
The list of Countries = USA, France, Italy
The States for USA = Michigan, Florida, California

lmer - BLUP prediction intervals
Dear all
I have a model that looks like this:
m1 <- lmer(Difference ~ 1+ (1|Examiner) + (1|Item), data=englisho.data)
I know it is not possible to estimate random effects but one can
obtain BLUPs of the conditional modes with
re1 <- ranef(m1, postVar=T)
And then dotplot(re1) for the examiner and item levels gives me a nice
prediction interval. But I would like to have the prediction

Create a new variable
Dear R-list,
Sorry for spamming the list lately, I am just learning the more advanced
aspects of R!
I have some data that looks like this:
Out Country1 Country 2 Country 3 ... CountryN
1 1 1 1 1
0 1 1 0 1
1 1 0 1 0
I want to create a new variable that counts the number of zeros in every
row whenever Out is equal to 1, and else it is a zero, so it would look
like this:

lmer() : crossed-random-effects specification
Dear all,
I want to estimate a crossed-random-effects model (i.e., measurements,
students, schools) where students migrate between schools over time.
I'm interested in the fixed effects of "SES", "age" and their
interaction on "read" (reading achievement) while accounting for the
sample design. Based on a previous post, I'm specifying my model as:

recursive methods for concatenating sets of files
Hello,
I would like to read sets of files within a folder, perhaps using recursive
methods.
Right now, I rename the files before import.
It would be even better to do this without renaming files, without providing
explicit filenames, perhaps by importing files based on chronology,
and translating each filename into a header?
Please excuse my ignorance, and help cure my clunky programming

political maps world maps in R, wrld_simpl
dear all,
I'm a newbie in map tools. I was asking to perform an apparently very
simple task.
I have a list of countries (about fifty all over in the world) scored
with a real positive value. Eg
Country score
Italy .56
UK .58
Korea .41
Mexico .63
...
I wish to plot geographical maps where every country is filled with a
color depending on his score.

Returning only a file path on Windows
I am choosing a file like this:
#Bring up file selection box
fn<-file.choose()
fp<-file.path(fn,fsep='\\')
Unfortunately, the file path contains the short file name and extension as
well. I had hoped to get only the path so I could make my own long
filenames (for output graphs) by concatenation with this file path.
Of course I can split the string and assemble the components from

how to plot two graphics in one window
Hello ,
Maybe this question you answered before, but i couldnt find something
indicated in the mailing list.
I wish to plot two graphics in one window, for example y=sinx and y=exp(x)
in the same windows, (the same interval for x).
Thanks .
Miguel.
